"The interesting bug fix is support for the upcoming "4.2" release of
the Tilera hypervisor, which by default launches Linux at privilege
level 2 instead of 1. The fix lets new and old hypervisors and
Linuxes interoperate more smoothly, so I've tagged it for
stable@kernel.org so that older Linuxes will be able to boot under the
newer hypervisor."

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

Cancelling kiocbs requires adding them to a per kioctx linked list,
which is one of the few things we need to take the kioctx lock for in
the fast path. But most kiocbs can't be cancelled - so if we just do
this lazily, we can avoid quite a bit of locking overhead.
While we're at it, instead of using a flag bit switch to using ki_cancel
itself to indicate that a kiocb has been cancelled/completed. This lets
us get rid of ki_flags entirely.

This removes the only in-tree user of aio retry. This will let us
remove the retry code from the aio core.
Removing retry is relatively easy as the USB gadget wasn't using it to
retry IOs at all. It always fully submitted the IO in the context of
the initial io_submit() call. It only used the AIO retry facility to
get the submitter's mm context for copying the result of a read back to
user space. This is easy to implement with use_mm() and a work struct,
much like kvm does with async_pf_execute() for get_user_pages().

Like the EHCI driver, OHCI supports a large number of different platform
glue drivers by directly including them, which causes problems with
conflicting macro definitions in some cases. As more ARM architecture
specific back-ends are required to coexist in a single build, we should
split those out into separate drivers. Unfortunately, the infrastructure
for that is still under development, so to give us more time, this uses
a separate *_PLATFORM_DRIVER macro for each ARM specific OHCI backend,
just like we already do on PowerPC and some of the other ARM platforms.
In linux-3.10, only the SPEAr and CNS3xxx back-ends would actually conflict
without this patch, but over time we would get more of them, so this
is a way to avoid having to patch the driver every time it breaks. We
should still split out all back-ends into separate loadable modules,
but that work is only needed to improve code size and cleanliness after
this patch, not for correctness.
While we're here, this fixes the incorrectly sorted error path
for the OMAP1 and OMAP3 backends to ensure we always unregister
the exact set of drivers that were registered before erroring out.

The Kconfig entry for USB_LPC32XX unconditionally selects USB_ISP1301,
which is now only visible when USB_PHY is also enabled.
This adds an appropriate dependency and enables USB_PHY in the msm
defconfig, avoiding these build errors:

The FT4232H used in the ST Micro Connect Lite has four hi-speed UART ports.
The first two ports are reserved for the JTAG interface.
We enable by default ports 2 and 3 as UARTs (where port 2 is a
conventional RS-232 UART)

Both phy-tegra-usb.c and ehci-tegra.c export symbols used by the other one,
which does not work if one of them or both are loadable modules, resulting
in an error like:
drivers/built-in.o: In function `utmi_phy_clk_disable':
drivers/usb/phy/phy-tegra-usb.c:302: undefined reference to `tegra_ehci_set_phcd'
drivers/built-in.o: In function `utmi_phy_clk_enable':

drivers/built-in.o: In function `utmi_phy_power_on':

This turns the interface into a one-way dependency by letting the tegra ehci
driver pass two function pointers for callbacks that need to be called by
the phy driver.

A lot of platform code calls into the usb phy core at the moment, which
does not work if it is built as a loadable module. This will hopefully
change when those platforms are all converted to DT based probing,
but for now, the easiest solution is to change it from "tristate"
to "bool".

Many cards based on CY7C68300A/B/C use the USB ID 04b4:6830 but only the
B and C variants (EZ-USB AT2LP) support the ATA Command Block
functionality, according to the data sheets. The A variant (EZ-USB AT2)
locks up if ATACB is attempted, until a typical 30 seconds timeout runs
out and a USB reset is performed.
https://bugs.launchpad.net/bugs/428469
It seems that one way to spot a CY7C68300A (at least where the card
manufacturer left Cypress' EEPROM default vaules, against Cypress'
recommendations) is to look at the USB string descriptor indices.
A http://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY7C68300A.pdf
B http://www.farnell.com/datasheets/43456.pdf
C http://www.cypress.com/?rID=14189
Note that a CY7C68300B/C chip appears as CY7C68300A if it is running
in Backward Compatibility Mode, and if ATACB would be supported in this
case there is anyway no way to tell which chip it really is.
For 5 years my external USB drive has been locking up for half a minute
when plugged in and ata_id is run by udev, or anytime hdparm or similar
is run on it.
Finally looking at the /correct/ datasheet I think I found the reason. I
am aware the quirk in this patch is a bit hacky, but the hardware
manufacturers haven't made it easy for us.

The current ST Micro Connect Lite uses the FT4232H hi-speed quad USB
UART FTDI chip. It is also possible to drive STM reference targets
populated with an on-board JTAG debugger based on the FT2232H chip with
the same STMicroelectronics tools.
For this reason, the ST Micro Connect Lite PIDs should be
ST_STMCLT_2232_PID: 0x3746
ST_STMCLT_4232_PID: 0x3747

Here are some late urgent fixes for v3.10 merge window.
All of these errors were introduced by recent commits
which are in linux-next.
f_obex, multi and cdc2 gadget drivers have learned to
return a proper error code when something goes wrong.
usb_bind_phy() was mistakenly placed into .init.text
section which caused Section mismatch warnings and undefined
reference compile errors.
f_source_sink had a copy-paste error which is now corrected.
g_zero got a memory leak plugged.
Two defconfigs got fixed to enable the newly introduced
CONFIG_USB_PHY.

The symbol usb_bind_phy is exported and annotated __init.
It looks like section mismatch. Fix by removing the
__init annotation of usb_bind_phy.

Use a more current logging style with dev_printk
where possible.
o Convert uses of US_DEBUGP to usb_stor_dbg
o Add "struct us_data *" to usb_stor_dbg uses
o usb_stor_dbg now uses struct device */dev_vprint_emit
o Removed embedded function names
o Coalesce formats
o Remove trailing whitespace
o Remove useless OOM messages
o Remove useless function entry/exit logging
o Convert some US_DEBUGP uses to dev_info and dev_dbg
Object size is slightly reduced when debugging
is enabled, slightly increased with no debugging
because some initialization and removal messages
are now always emitted.
