6f976267da of: add missing major vendors
Looking at the current vendor strings used in the kernel's .dts/.dtsi
files, some vendors are used a high number of times without
being documented. Document the ones that are used more than 10 times.

Note: a few inconsistencies were found, and thus not documented.
Here is the list:
- mrvl: duplicates "marvell"
- st-ericsson: duplicates "ste" _and_ "stericsson"
- pci8086: seems to be a unfortunate alias for "intel"
- pnpPNP: used on PowerPC?

926b65e20d clocksource: keystone: add bindings for keystone timer
This patch provides bindings for the 64-bit timer in the KeyStone
architecture devices. The timer can be configured as a general-purpose 64-bit
timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
timers, each half can operate in conjunction (chain mode) or independently
(unchained mode) of each other.

It is global timer is a free running up-counter and can generate interrupt
when the counter reaches preset counter values.

75b57ecf9d of: Make device nodes kobjects so they show up in sysfs
Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.

v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
    Fix updating property values in sysfs
v4: Fixed build error on Powerpc
    Fixed handling of dynamic nodes on powerpc
v3: Fixed handling of duplicate attribute and child node names
v2: switch to using sysfs bin_attributes which solve the problem of
    reporting incorrect property size.

79e615420c ARM: SoC fixes for 3.14-rc
A collection of fixes for ARM platforms. A little large due to us missing to
 do one last week, but there's nothing in particular here that is in itself
 large and scary.
 
 Mostly a handful of smaller fixes all over the place. The majority is made
 up of fixes for OMAP, but there are a few for others as well. In particular,
 there was a decision to rename a binding for the Broadcom pinctrl block that
 we need to go in before the final release since we then treat it as ABI.

 been implemented, some randconfig build errors have been fixed,
 and it was taught about the new generic phy layer.
 
 MUSB on AM335x now supports isochronous transfers thanks to
 George Cherian's work.
 
 The atmel_usba driver got two crash fixes: one when no endpoint
 was specified in DeviceTree data and another when stopping the UDC
 in DEBUG builds.
 
 Function FS got a much needed fix to ffs_epfile_io() which was
 copying too much data to userspace in some cases.

bfe24b9cbe Merge branch 'imx-drm-staging' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into staging-next
Russell writes:

This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.

The result is that more TODO entries are now removed.  While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.

However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of.  Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cf).

Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.

I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.

The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.

David Howells says:

====================
net-next: AF_RXRPC fixes and development

Here are some AF_RXRPC fixes:

 (1) Fix to remove incorrect checksum calculation made during recvmsg().  It's
     unnecessary to try to do this there since we check the checksum before
     reading the RxRPC header from the packet.

 (2) Fix to prevent the sending of an ABORT packet in response to another
     ABORT packet and inducing a storm.

 (3) Fix UDP MTU calculation from parsing ICMP_FRAG_NEEDED packets where we
     don't handle the ICMP packet not specifying an MTU size.

And development patches:

 (4) Add sysctls for configuring RxRPC parameters, specifically various delays
     pertaining to ACK generation, the time before we resend a packet for
     which we don't receive an ACK, the maximum time a call is permitted to
     live and the amount of time transport, connection and dead call
     information is cached.

 (5) Improve ACK packet production by adjusting the handling of ACK_REQUESTED
     packets, ignoring the MORE_PACKETS flag, delaying the production of
     otherwise immediate ACK_IDLE packets and delaying all ACK_IDLE production
     (barring the call termination) to half a second.

 (6) Add more sysctl parameters to expose the Rx window size, the maximum
     packet size that we're willing to receive and the number of jumbo rxrpc
     packets we're willing to handle in a single UDP packet.

 (7) Request ACKs on alternate DATA packets so that the other side doesn't
     wait till we fill up the Tx window.

 (8) Use a RCU hash table to look up the rxrpc_call for an incoming packet
     rather than stepping through a hierarchy involving several spinlocks.

c7e64b9ce0 powerpc/powernv Platform dump interface
This enables support for userspace to fetch and initiate FSP and
Platform dumps from the service processor (via firmware) through sysfs.

Based on original patch from Vasant Hegde <hegdevasant@linux.vnet.ibm.com>

Flow:
  - We register for OPAL notification events.
  - OPAL sends new dump available notification.
  - We make information on dump available via sysfs
  - Userspace requests dump contents
  - We retrieve the dump via OPAL interface
  - User copies the dump data
  - userspace sends ack for dump
  - We send ACK to OPAL.

sysfs files:
  - We add the /sys/firmware/opal/dump directory
  - echoing 1 (well, anything, but in future we may support
    different dump types) to /sys/firmware/opal/dump/initiate_dump
    will initiate a dump.
  - Each dump that we've been notified of gets a directory
    in /sys/firmware/opal/dump/ with a name of the dump type and ID (in hex,
    as this is what's used elsewhere to identify the dump).
  - Each dump has files: id, type, dump and acknowledge
    dump is binary and is the dump itself.
    echoing 'ack' to acknowledge (currently any string will do) will
    acknowledge the dump and it will soon after disappear from sysfs.

OPAL APIs:
  - opal_dump_init()
  - opal_dump_info()
  - opal_dump_read()
  - opal_dump_ack()
  - opal_dump_resend_notification()

Currently we are only ever notified for one dump at a time (until
the user explicitly acks the current dump, then we get a notification
of the next dump), but this kernel code should "just work" when OPAL
starts notifying us of all the dumps present.

774fea1a38 powerpc/powernv: Read OPAL error log and export it through sysfs
Based on a patch by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

This patch adds support to read error logs from OPAL and export
them to userspace through a sysfs interface.

We export each log entry as a directory in /sys/firmware/opal/elog/

Currently, OPAL will buffer up to 128 error log records, we don't
need to have any knowledge of this limit on the Linux side as that
is actually largely transparent to us.

Each error log entry has the following files: id, type, acknowledge, raw.
Currently we just export the raw binary error log in the 'raw' attribute.
In a future patch, we may parse more of the error log to make it a bit
easier for userspace (e.g. to be able to display a brief summary in
petitboot without having to have a full parser).

If we have >128 logs from OPAL, we'll only be notified of 128 until
userspace starts acknowledging them. This limitation may be lifted in
the future and with this patch, that should "just work" from the linux side.

A userspace daemon should:
- wait for error log entries using normal mechanisms (we announce creation)
- read error log entry
- save error log entry safely to disk
- acknowledge the error log entry
- rinse, repeat.

On the Linux side, we read the error log when we're notified of it. This
possibly isn't ideal as it would be better to only read them on-demand.
However, this doesn't really work with current OPAL interface, so we
read the error log immediately when notified at the moment.

I've tested this pretty extensively and am rather confident that the
linux side of things works rather well. There is currently an issue with
the service processor side of things for >128 error logs though.

The original documentation was very unclear.

The code fix is presumably related to the formerly unclear
documentation: SOCK_TIMESTAMPING_RX_SOFTWARE has no effect on
__sock_recv_timestamp's behavior, so calling __sock_recv_ts_and_drops
from sock_recv_ts_and_drops if only SOCK_TIMESTAMPING_RX_SOFTWARE is
set is pointless.  This should have no user-observable effect.

07f2b6e038 dm thin: ensure user takes action to validate data and metadata consistency
If a thin metadata operation fails the current transaction will abort,
whereby causing potential for IO layers up the stack (e.g. filesystems)
to have data loss.  As such, set THIN_METADATA_NEEDS_CHECK_FLAG in the
thin metadata's superblock which:
1) requires the user verify the thin metadata is consistent (e.g. use
   thin_check, etc)
2) suggests the user verify the thin data is consistent (e.g. use fsck)

The only way to clear the superblock's THIN_METADATA_NEEDS_CHECK_FLAG is
to run thin_repair.

On metadata operation failure: abort current metadata transaction, set
pool in read-only mode, and now set the needs_check flag.

As part of this change, constraints are introduced or relaxed:
* don't allow a pool to transition to write mode if needs_check is set
* don't allow data or metadata space to be resized if needs_check is set
* if a thin pool's metadata space is exhausted: the kernel will now
  force the user to take the pool offline for repair before the kernel
  will allow the metadata space to be extended.

Also, update Documentation to include information about when the thin
provisioning target commits metadata, how it handles metadata failures
and running out of space.

eb9cf4e8ec Revert irqchip: irq-dove: Add PMU interrupt controller
This reverts commit 40b367d95f.

Russell King has raised the idea of creating a proper PMU driver for
this SoC that would incorporate the functionality currently in this
driver. It would also cover the use case for the graphics subsystem on
this SoC.

To prevent having to maintain the devicetree ABI for this limited
interrupt-handler driver, we revert the driver before it hits a mainline
tagged release (eg v3.15).

a41a8927e7 hwmon: (lm95245) Make temp2_crit_hyst read-only
The hysteresis register is shared among both temperature sensors.
This means changing one also affects the other. To avoid confusion,
established way to express this is to make only the first instance writable
and keep all other instances as read-only. Otherwise users may be
confused that changing the second writable value also affects the first,
while it is more obvious that a writable value may affect a different
read-only value.

821047c405 can: remove CAN FD compatibility for CAN 2.0 sockets
In commit e2d265d3b5 (canfd: add support for CAN FD in CAN_RAW sockets)
CAN FD frames with a payload length up to 8 byte are passed to legacy
sockets where the CAN FD support was not enabled by the application.

After some discussions with developers at a fair this well meant feature
leads to confusion as no clean switch for CAN / CAN FD is provided to the
application programmer. Additionally a compatibility like this for legacy
CAN_RAW sockets requires some compatibility handling for the sending, e.g.
make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?).

This will become a mess when people start to develop applications with
real CAN FD hardware. This patch reverts the bad compatibility code
together with the documentation describing the removed feature.

588858c4df devicetree: Add Xilinx XADC binding documentation
The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.

Each of them needs:
	* A address range where the registers are mapped
	* An interrupt number for the device interrupt
	* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
	  clock, for the AXI softmacro it is the AXI bus interface clock.

Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.

7a962a4b6e memory: ti-aemif: add bindings for AEMIF driver
Add bindings for TI Async External Memory Interface (AEMIF) controller.

The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
provide a glue-less interface to a variety of asynchronous memory devices like
ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
can be accessed via 4 chip selects with 64M byte access per chip select.

We are not encoding CS number in reg property, it's memory partition number.
The CS number is encoded for Davinci NAND node using standalone property
"ti,davinci-chipselect" and we need to provide two memory ranges to it,
as result we can't encode CS number in "reg" for AEMIF child devices
(NAND/NOR/etc), as it will break bindings compatibility.

In this patch, NAND node is used just as an example of child node.

beb74bb087 spi: sh-msiof: Add support for R-Car H2 and M2
Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2
(r8a7791) SoCs.

Binding documentation:
  - Add future-proof "renesas,msiof-<soctype>" compatible values,
  - The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2,
  - "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for
    soctype-specific bindings,
  - Add example bindings.

Implementation:
  - MSIOF on R-Car H2 and M2 requires the transmission of dummy data if
    data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write
    dummy transmission data to SITFDR" in paragraph "Transmit and Receive
    Procedures" of the Hardware User's Manual).
  - As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR
    register (Receive Clock Select Register), and some bits in the RMDR1
    (Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2)
    registers.
  - Use the recently introduced SPI_MASTER_MUST_TX flag to enable support
    for dummy transmission in the SPI core, and to differentiate from other
    MSIOF implementations in code paths that need this.
  - New DT compatible values ("renesas,msiof-r8a7790" and
    "renesas,msiof-r8a7791") are added, as well as new platform device
    names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof").
  - The default RX FIFO size is 256 words on R-Car H2 and M2.

This is loosely based on a set of patches from Takashi Yoshii
<takasi-y@ops.dti.ne.jp>.

e2b32e6785 x86, kaslr: randomize module base load address
Randomize the load address of modules in the kernel to make kASLR
effective for modules.  Modules can only be loaded within a particular
range of virtual address space.  This patch adds 10 bits of entropy to
the load address by adding 1-1024 * PAGE_SIZE to the beginning range
where modules are loaded.

The single base offset was chosen because randomizing each module
load ends up wasting/fragmenting memory too much. Prior approaches to
minimizing fragmentation while doing randomization tend to result in
worse entropy than just doing a single base address offset.

Example kASLR boot without this change, with a single module loaded:
---[ Modules ]---
0xffffffffc0000000-0xffffffffc0001000           4K     ro     GLB x  pte
0xffffffffc0001000-0xffffffffc0002000           4K     ro     GLB NX pte
0xffffffffc0002000-0xffffffffc0004000           8K     RW     GLB NX pte
0xffffffffc0004000-0xffffffffc0200000        2032K                   pte
0xffffffffc0200000-0xffffffffff000000        1006M                   pmd
---[ End Modules ]---

Example kASLR boot after this change, same module loaded:
---[ Modules ]---
0xffffffffc0000000-0xffffffffc0200000           2M                   pmd
0xffffffffc0200000-0xffffffffc03bf000        1788K                   pte
0xffffffffc03bf000-0xffffffffc03c0000           4K     ro     GLB x  pte
0xffffffffc03c0000-0xffffffffc03c1000           4K     ro     GLB NX pte
0xffffffffc03c1000-0xffffffffc03c3000           8K     RW     GLB NX pte
0xffffffffc03c3000-0xffffffffc0400000         244K                   pte

The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the

aa256f8d0d Second round of IIO new driver, functionality and cleanups for the 3.15 series.
There are a few fixes in here that might, earlier in a cycle, have gone
 to Greg as fixes. Given they are either minor or have never actually
 been observed as causing trouble (the locking bug in the event code) and
 are invasive, I have included them in this pull request, targeting the
 3.15 merge window instead.
 
 The rest are pretty uncontroversial new drivers, a handy little tool for
 the example code in our documentation and little cleanups.
 
 New drivers
 * Freescale Vybrid and i.MX6SLX ADC driver.
 * HID Sensor hub proximity sensors.
 * HID Sensor hub pressure sensors.
 * LPS25H Pressure sensors added to the ST micro pressure sensor driver.
 
 New functionality
 * lsiio tool.  This is added to the staging tree as we haven't yet moved
   the example code it sits with out.  Moving this code out is now a reasonably
   high priority but holding up this tool in the meantime did not seem
   worthwhile.
 * mag3110 - add missing scale factor for temperature output to userspace.
 
 Cleanups
 * Fix a bug in the event reporting in which a spin lock might be held over
   when a sleep occured.  A similar bug was found by Lars in the buffer code.
   It has not to our knowledge been observed as actually occuring and is
   a little too invasive to push out as a fix.
 * Drop the IIO_ST macro after clearing out all users.  This macro was a very
   bad idea leading to a number of bugs after it stopped covering all elements
   of the structure being assigned and people started making assumptions about
   what it did cover.  Glad to see it go!
 * Avoid applying extended name to shared attributes as it makes no sense.
   No in tree drivers were using the combination, hence not pushed out as
   a fix.
 * ad799x - move to devm_request_threaded_irq to reduce boilerplate clean up.
 * bma180 - make the low_pass_filter_3db_frequency info element shared rather
   than per attribute.  The old approach was valid but not as clean as it might
   be and was setting a bad example.  Hence the cleanup.
 * mxs-lradc - propogate the error code form a platform_get_irq call rather than
   eating it up by returning -EINVAL on all errors.
 * ad799x - typo fix in the copyright message. Either that or Michael was
   asserting a copyright that moved backwards in time by about a thousand years.
 * ad799x - use a regulator for vref rather than platform data.  The driver
   dates from just as the regulator framework was coming into common use so
   provides an alternative way of specifying the reference voltage.  We no
   longer need that approach so drop it in favour of a regulator only approach.
 * max1363 - some internal vref values were out by a small amount.  The effect
   would have been tiny and no one noticed hence not pushing this through as
   a fix.
 * core - replace some pointless goto error_ret (with no clean up) lines with
   direct returns.  This is my bad coding style so I'm glad to see it cleaned
   up.
 * core - avoid a kasprintf that just directly prints a string with no
   formatting elements.  This has always been there but Lars just noticed it.
   Oops.

b5f6517948 spi: sunxi: Add Allwinner A10 SPI controller driver
The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI
controller.

Unfortunately, this SPI controller, even though quite similar, is significantly
different from the recently supported A31 SPI controller (different registers
offset, split/merged registers, etc.). Supporting both controllers in a single
driver would be unreasonable, hence the addition of a new driver.

Like its more recent counterpart, it supports DMA, but the driver only does PIO
until we have a dmaengine driver for this platform.

This patch adds support for the ahci sata controler found on Allwinner A10

Orignally written by Olliver Schinagl using the approach of having a platform

driven by ahci_platform.c, as done by ahci_imx.c .

Refactored by Hans de Goede to add most of the non sunxi specific functionality
to ahci_platform.c and use a platform_data pointer from of_device_id for the
sunxi specific bits.

bc69b8adfe irqchip: armada-370-xp: Setup a chained handler for the MPIC
The new Armada 375 and Armada 38x Marvell SoCs are based on Cortex-A9
CPU cores and use the ARM GIC as their main interrupt controller.
However, for various purposes (wake-up from suspend, MSI interrupts),
they have kept a separate MPIC interrupt controller, acting as a slave
to the GIC. This MPIC was already used as the primary controller on
previous Marvell SoCs, so this commit extends the existing driver to
allow the MPIC to be used as a GIC slave.

Pull PCI updates from Bjorn Helgaas:
 "The most interesting thing here is the change to enable INTx (by
  clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
  Apparently the Baytrail BIOS does this, which means EHCI doesn't work.

  Also, fix an AHCI MSI regression and other issues with the recent MSI
  changes.  This also adds pci_enable_msi_exact() and
  pci_enable_msix_exact(), which aren't regression fixes, but will keep
  us from touching drivers twice (once to stop using the deprecated
  pci_enable_msi(), etc., and again to use the *_exact() variants).

  There's also a minor MVEBU fix.

e8f08ee0ad DT: net: document Ethernet bindings in one place
This patch is an attempt to gather the Ethernet related bindings in one file,
like it's done in the MMC and some other subsystems. It should save some of
the trouble of documenting several properties over and over in each binding
document, instead only making reference to the main file.

I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR)
standard as a base for the properties description, also documenting some ad-hoc
properties that have been introduced over time despite having direct analogs in
ePAPR.

13ac34a886 bonding: permit using arp_validate with non-ab modes
Currently it's disabled because it's sometimes hard, in typical configs, to
make it work - because of the nature how the loadbalance modes work - as
it's hard to deliver valid arp replies to correct slaves by the switch.

However we still can use arp_validation in loadbalance with several other
configs, per example with arp_validate == 2 for backup with one broadcast
domain, without the switch(es) doing any balancing - this way we'd be (a
bit more) sure that the slave is up.

So, enable it to let users decide which one works/suits them best. Also
correct the mode limitation from BOND_OPT_ARP_VALIDATE.

34018fd419 gianfar: Remove sysfs stubs for FIFOCFG and stashing
Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI
(stashing) config registers, as these registers may only
be configured after a MAC reset, with the controller stopped
(i.e. during hw init, at probe() time).  The current sysfs
stubs allow on-the-fly updates of these registers (the locking
measures are useless and only add unecessary code).

Changing these registers is discouraged. Only the default values
will be used instead.

Moreover, the stashing (ATTRELI) configuration options were
effectively disabled (didn't get to the hw anyway if changed)
because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING)
were "accidentally" cleared during probe().

b075dd40c9 Bluetooth: allocate static minor for vhci
Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
driver) added the module alias to hci_vhci module so it's possible to
create the /dev/vhci node. However creating an alias without
specifying the minor doesn't allow us to create the node ahead,
triggerring module auto-load when it's first accessed.

Starting with depmod from kmod 16 we started to warn if there's a
devname alias without specifying the major and minor.

Let's do the same done for uhid, kvm, fuse and others, specifying a
fixed minor. In systems with systemd as the init the following will
happen: on early boot systemd will call "kmod static-nodes" to read
/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
first accessed these "dead" nodes will trigger the module loading.

9b2b3bf531 Documentation/memory-barriers.txt: Need barriers() for some control dependencies
Current compilers can "speculate" stores in the case where both legs
of the "if" statement start with identical stores.  Because the stores
are identical, the compiler knows that the store will unconditionally
execute regardless of the "if" condition, and so the compiler is within
its rights to hoist the store to precede the condition.  Such hoisting
destroys the control-dependency ordering.  This ordering can be restored
by placing a barrier() at the beginning of each leg of the "if" statement.
This commit adds this requirement to the control-dependencies section.

This commit adds a simple ASoC board driver fo the Armada 370
Development Board, which connects the audio unit of the Armada 370 SoC
to the I2C-based CS42L51.

For now, only the analog audio input and output through the CS42L51
are supported, but a followup patch adds S/PDIF support to this
driver.

We deprecated pci_enable_msi() in 302a2523c2 ("PCI/MSI: Add
pci_enable_msi_range() and pci_enable_msix_range()").

But we changed our minds after noticing that:

  - pci_enable_msi() doesn't have confusing return values like
    pci_enable_msi_block() and pci_enable_msix() did, and

  - pci_enable_msi() has a hundred or so callers that we don't want to
    change.

This adds back the pci_enable_msi() documentation.

4dde507fc1 ACPICA: Add boot option to disable auto return object repair
Sometimes, there might be bugs caused by unexpected AML which is compliant
to the Windows but not compliant to the Linux implementation.

There is a predefined validation mechanism implemented in ACPICA to repair
the unexpected AML evaluation results that are caused by the unexpected
AMLs.  For example, BIOS may return misorder _CST result and the repair
mechanism can make an ascending order on the returned _CST package object
based on the C-state type.
This mechanism is quite useful to implement an AML interpreter with better
compliance with the real world where Windows is the de-facto standard and
BIOS codes are only tested on one platform thus not compliant to the
ACPI specification.

But if a compliance issue hasn't been figured out yet, it will be
difficult for developers to identify if the unexpected evaluation result
is caused by this mechanism or by the AML interpreter.
For example, _PR0 is expected to be a control method, but BIOS may use
Package: "Name(_PR0, Package(1) {P1PR})".
This boot option can disable the predefined validation mechanism so that
developers can make sure the root cause comes from the parser/executer.

This patch adds a new kernel parameter to disable this feature.

A build test has been made on a Dell Inspiron mini 1100 (i386 z530)
machine when this patch is applied and the corresponding boot test is
performed w/ or w/o the new kernel parameter specified.
