perf record: Support s390 random socket_id assignment
On s390 the socket identifier assigned to a CPU identifier is random and (depending on the configuration of the LPAR) may be higher than the CPU identifier. This is currently not supported. Fix this by allowing arbitrary socket identifiers being assigned to CPU id. Output before: [root@p23lp27 perf]# ./perf report --header -I -v ... socket_id number is too big.You may need to upgrade the perf tool. Error: The perf.data file has no samples! # ======== # captured on : Tue May 29 09:29:57 2018 # header version : 1 ... # Core ID and Socket ID information is not available ...

uprobes/x86: Remove incorrect WARN_ON() in uprobe_init_insn()
insn_get_length() has the side-effect of processing the entire instruction but only if it was decoded successfully, otherwise insn_complete() can fail and in this case we need to just return an error without warning.

perf/urgent fixes and improvements:
perf stat:
. Add --interval-clear option, to provide a 'watch' like printing (Jiri Olsa)
. Fix metric column header display alignment (Jiri Olsa)
. Improve error messages for default attributes, providing better output
for error in command lines such as:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
\___ unknown term
Where the "event syntax error" line now appears (Jiri Olsa)
perf script:
. Show hw-cache events too (Seeteena Thoufeek)
perf c2c:
. Fix data dependency problem in layout of 'struct c2c_hist_entry', where
its member 'struct hist_entry' must be at the end because it has a ZLA
as its last member, that gets space when handling callchains (Jiri Olsa)
Core:
- We cannot assume that a 'struct perf_evsel' is to be obtained from a
container_of operation on a 'struct hists' as there are tools, such as
'perf c2c' that uses 'struct hist' instances without having them in
container structs that also have 'struct perf_evsel' in a particular
layout, so provide a different way of figuring out if a 'struct hists'
and 'struct hist_entry' have callchains (Arnaldo Carvalho de Melo)
- Fix error index in the PMU event parser, so that error messages can
point to the problematic token (Jiri Olsa)

Pull x86 updates and fixes from Thomas Gleixner: - Fix the (late) fallout from the vector management rework causing hlist corruption and irq descriptor reference leaks caused by a missing sanity check. The straight forward fix triggered another long standing issue to surface. The pre rework code hid the issue due to being way slower, but now the chance that user space sees an EBUSY error return when updating irq affinities is way higher, though quite a bunch of userspace tools do not handle it properly despite the fact that EBUSY could be returned for at least 10 years. It turned out that the EBUSY return can be avoided completely by utilizing the existing delayed affinity update mechanism for irq remapped scenarios as well. That's a bit more error handling in the kernel, but avoids fruitless fingerpointing discussions with tool developers. - Decouple PHYSICAL_MASK from AMD SME as its going to be required for the upcoming Intel memory encryption support as well. - Handle legacy device ACPI detection properly for newer platforms - Fix the wrong argument ordering in the vector allocation tracepoint - Simplify the IDT setup code for the APIC=n case - Use the proper string helpers in the MTRR code - Remove a stale unused VDSO source file - Convert the microcode update lock to a raw spinlock as its used in atomic context. * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/intel_rdt: Enable CMT and MBM on new Skylake stepping x86/apic/vector: Print APIC control bits in debugfs genirq/affinity: Defer affinity setting if irq chip is busy x86/platform/uv: Use apic_ack_irq() x86/ioapic: Use apic_ack_irq() irq_remapping: Use apic_ack_irq() x86/apic: Provide apic_ack_irq() genirq/migration: Avoid out of line call if pending is not set genirq/generic_pending: Do not lose pending affinity update x86/apic/vector: Prevent hlist corruption and leaks x86/vector: Fix the args of vector_alloc tracepoint x86/idt: Simplify the idt_setup_apic_and_irq_gates() x86/platform/uv: Remove extra parentheses x86/mm: Decouple dynamic __PHYSICAL_MASK from AMD SME x86: Mark native_set_p4d() as __always_inline x86/microcode: Make the late update update_lock a raw lock for RT x86/mtrr: Convert to use strncpy_from_user() helper x86/mtrr: Convert to use match_string() helper x86/vdso: Remove unused file x86/i8237: Register device based on FADT legacy boot flag |

Merge branch 'proc-cmdline'
Merge proc_cmdline simplifications. This re-writes the get_mm_cmdline() logic to be rather simpler than it used to be, and makes the semantics for "cmdline goes past the end of the original area" more natural. You _can_ use prctl(PR_SET_MM) to just point your command line somewhere else entirely, but the traditional model is to just edit things in place and that still needs to continue to work. At least this way the code makes some sense. * proc-cmdline: fs/proc: simplify and clarify get_mm_cmdline() function fs/proc: re-factor proc_pid_cmdline_read() a bit |

This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm.

Staging/IIO patches for 4.18-rc1
Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog
has the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about
this code since it moved to staging last year, and if it needs
to come back, it can be reverted.
- lustre file system is removed. I've ranted at the lustre
developers about once a year for the past 5 years, with no
real forward progress at all to clean things up and get the
code into the "real" part of the kernel. Given that the
lustre developers continue to work on an external tree and try
to port those changes to the in-kernel tree every once in a
while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the
time working in their out-of-tree location and get things
cleaned up properly to get merged into the tree correctly at a
later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems.

libnvdimm for 4.18
* DAX broke a fundamental assumption of truncate of file mapped pages.
The truncate path assumed that it is safe to disconnect a pinned page
from a file and let the filesystem reclaim the physical block. With DAX
the page is equivalent to the filesystem block. Introduce
dax_layout_busy_page() to enable filesystems to wait for pinned DAX
pages to be released. Without this wait a filesystem could allocate
blocks under active device-DMA to a new file.
* DAX arranges for the block layer to be bypassed and uses
dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
However, the memcpy_mcsafe() facility is available through the pmem
block driver. In order to safely handle media errors, via the DAX
block-layer bypass, introduce copy_to_iter_mcsafe().
* Fix cache management policy relative to the ACPI NFIT Platform
Capabilities Structure to properly elide cache flushes when they are not
necessary. The table indicates whether CPU caches are power-fail
protected. Clarify that a deep flush is always performed on
REQ_{FUA,PREFLUSH} requests.

regulator: Updates for v4.18
Quite a lot of core work this time around, though not 100% successful. We gained support for runtime mode changes thanks to David Collins and improved support for write only regulators (ones where we can't read back the configuration) from Douglas Anderson. There's been quite a bit of work from Linus Walleij on converting from specfying GPIOs by numbers to descriptors. Sadly the testing turned out to be less good than we had hoped and so a lot of this had to be reverted. We also have the start of updates to use coupled regulators from Maciej Purski, unfortunately there are further problems there so the last couple of patches have been reverted. We also have new drivers for BD71837 and SY8106A devices, SAW regulators on Qualcomm SPMI and dropped support for some preproduction chips that never made it to market from the AB8500 driver. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlsarcETHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0B4HB/9MFV/MK7Hw2hsVCX3qWTiH4tJ/X0MG tGz1PfmbH0CJ9ly5g+rvCoT+1/s7BydKzi1cd1RHnimBv2U1XagwSny3LNEcJs2Q pmhpGViakkQI/Y2h+u/j0Jk1nE+jTiKk+1ozUB7YnPekrGyQlf7TMhvKOLTvLKyX 56jdNxcW0MgSnXV2N6y4NpWhgvrQwvKjacTxV5iX7WP2rnK2WNFeG7Q859buhtI0 znRi+tO5hZsw5T44ickdPfotZn+i5o7MYLCkkaA2h1EwtpbYwVINfUjp3KtuyFhH 3B9GmCsjjN2Z2eInnkpzWfVXK2S1Vlp6+ka2FSs+U/4rVdd3Bw2KkblS =Ftua -----END PGP SIGNATURE----- Merge tag 'regulator-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "Quite a lot of core work this time around, though not 100% successful.

nvme: cleanup double shift issue
The problem here is that set_bit() and test_bit() take a bit number so we should be passing 0 but instead we're passing (1 << 0) which leads to a double shift. It doesn't cause a runtime bug in the current code because it's done consistently and we only set that one bit. I decided to just re-use NVME_AER_NOTICE_NS_CHANGED instead of introducing a new define for this.

nvme-pci: make CMB SQ mod-param read-only
A controller reset after a run time change of the CMB module parameter breaks the driver. An 'on -> off' will have the driver use NULL for the host memory queue, and 'off -> on' will use mismatched queue depth between the device and the host. We could fix both, but there isn't really a good reason to change this at run time anyway, compared to at module load time, so this patch makes parameter read-only after after modprobe.

nvme-pci: queue creation fixes
We've been ignoring NVMe error status on queue creations. Fortunately they are uncommon, but we should handle these anyway. This patch adds checks for the a positive error return value that indicates an NVMe status.

- cmpwait() WFE optimisation to avoid some spurious wakeups
- L1_CACHE_BYTES reverted back to 64 (for performance reasons that have
to do with some network allocations) while keeping ARCH_DMA_MINALIGN
to 128. cache_line_size() returns the actual hardware Cache Writeback

This is the bulk of GPIO changes for the v4.18 development
cycle. Core changes: - We have killed off VLA from the core library and all drivers. The background should be clear for everyone at this point: https://lwn.net/Articles/749064/ Also I just don't like VLA's, kernel developers hate it when compilers do things behind their back. It's as simple as that. I'm sorry that they even slipped in to begin with. Kudos to Laura Abbott for exorcising them. - Support GPIO hogs in machines/board files. New drivers and chip support: - R-Car r8a77470 (RZ/G1C) - R-Car r8a77965 (M3-N) - R-Car r8a77990 (E3) - PCA953x driver improvements to accomodate more variants. Improvements and new features: - Support one interrupt per line on port A in the DesignWare dwapb driver. Misc: - Random cleanups, right header files in the drivers, some size optimizations etc. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbGOMeAAoJEEEQszewGV1zGR0P/Rq/Mh6BRum7kZee8v22aKJE imtSamaVk7eOSdLC00VLvJ5QYJBMWz2GV5ZJkaxAwHBh1GhfddTDj35uXoOkRRWs vRXSYthujluGJ5YYfRNrXZhD4ahVYPnJV5XxLy4OF+aQBAd4jjRAqXLhQT1PVK9Q AQD/BOjToxrjgPREaLX9sQTW8DbICmjRhEWieJoQab2mZC+qD/aCen0rkj+UD0Qu wQRk5mSEsrC0qmWNS/rhzFa7/nRa4qWOMkHxim7/GqwGzgOTpv+TctmQOqMUjHqq k0ikVgBfZbaz3MqcuqLbKJ00mRK6G/yQIlECP4xcMbxKRxXucJj1ytOedIdG4nJE 5porXbW1d1bIhv3Zv8tt7vh00x+mEF+hv6p8DUa9ppe7qwsdbhUdzeczeyR8eM7U ZBi80jMJfp9wEugZ0F8syIUs3PPgp7y461hJDbZRuHp4P4jmpdUBMAF4XvWl6XPy DAlPHnSc2ZNaqWJtfc1ja4e6DlwltEV81Sd9Y0clLhkD95k95gZ7EzoyGPAIO4FG ir0getZE1mfh9K/EfkTOkcKHJh3b5rA5TiSbTVVaPO9SzqPtIK+xhDJI0r9IJkW1 XKgScOaJqpYEe2Y/Y/ezfnjxDLVxwOz6R77GsZCle1uPevOcxqN9fmjEn7gGYzmX PDf5pOuRrWApqix4a3Jr =Ly/0 -----END PGP SIGNATURE----- Merge tag 'gpio-v4.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.18 development cycle.

perf script: Show hw-cache events
'perf script' fails to report hardware cache events (PERF_TYPE_HW_CACHE)
where as 'perf report' shows the samples. Fix it. Ex,
# perf record -e L1-dcache-loads ./a.out
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.008 MB perf.data (11 samples)]
Before patch:
# perf script | wc -l
0
After patch:
# perf script | wc -l
11

perf c2c: Keep struct hist_entry at the end of struct c2c_hist_entry
Exactly as the comment just before 'struct c2c_hist_entry" says, i.e.
the last entry in struct hist_entry is a zero length array, that when
allocating space for hist_entry gets extra space if callchains are in
use, which, if hist_entry is not at the end of c2c_hist_entry, the
members after it gets corrupted when callchains get added to the rb
trees collecting them, etc.
