[PATCH 3.18 04/39] PCI: designware: Reject MSI-X IRQs

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

From: Lucas Stach <l.stach@pengutronix.de>

commit 19c5392eb1c1e81188e898400c0e8258827eb160 upstream.

The DesignWare PCIe MSI hardware does not support MSI-X IRQs.  Setting
those up failed as a side effect of a bug which was fixed by 91f8ae823f2b
("PCI: designware: Setup and clear exactly one MSI at a time").

Now that this bug is fixed, MSI-X IRQs need to be rejected explicitly;
otherwise devices trying to use them may end up with incorrectly working
interrupts.

[PATCH 3.18 06/39] PCI: Handle read-only BARs on AMD CS553x devices

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Myron Stowe <myron.stowe@redhat.com>

commit 06cf35f903aa6da0cc8d9f81e9bcd1f7e1b534bb upstream.

Some AMD CS553x devices have read-only BARs because of a firmware or
hardware defect.  There's a workaround in quirk_cs5536_vsa(), but it no
longer works after 36e8164882ca ("PCI: Restore detection of read-only
BARs").  Prior to 36e8164882ca, we filled in res->start; afterwards we
leave it zeroed out.  The quirk only updated the size, so the driver tried
to use a region starting at zero, which didn't work.

Expand quirk_cs5536_vsa() to read the base addresses from the BARs and
hard-code the sizes.

On Nix's system BAR 2's read-only value is 0x6200.  Prior to 36e8164882ca,
we interpret that as a 512-byte BAR based on the lowest-order bit set.  Per
datasheet sec 5.6.1, that BAR (MFGPT) requires only 64 bytes; use that to
avoid clearing any address bits if a platform uses only 64-byte alignment.

[bhelgaas: changelog, reduce BAR 2 size to 64]

[PATCH 3.18 07/39] spi: spi-fsl-dspi: Remove usage of devm_kzalloc

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bhuvanchandra DV <bhuvanchandra.dv@toradex.com>

commit 973fbce69ed8e79b5fe3ad19cfecb581a7ef8048 upstream.

devm_* API was supposed to be used only in probe function call.
Memory is allocated at 'probe' and free automatically at 'remove'.
Usage of devm_* functions outside probe sometimes leads to memory leak.
Avoid using devm_kzalloc in dspi_setup_transfer and use kzalloc instead.
Also add the dspi_cleanup function to free the controller data upon
cleanup.

[PATCH 3.18 08/39] spi: imx: use pio mode for i.mx6dl

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Robin Gong <b38343@freescale.com>

commit a02bb401f8ae264be782ee57d98bdd99f14c8022 upstream.

For TKT238285 hardware issue which may cause txfifo store data twice can only
be caught on i.mx6dl, we use pio mode instead of DMA mode on i.mx6dl.

[PATCH 3.18 09/39] sd: Fix max transfer length for 4k disks

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian King <brking@linux.vnet.ibm.com>

commit 3a9794d32984b67a6d8992226918618f0e51e5d5 upstream.

The following patch fixes an issue observed with 4k sector disks
where the max_hw_sectors attribute was getting set too large in
sd_revalidate_disk. Since sdkp->max_xfer_blocks is in units
of SCSI logical blocks and queue_max_hw_sectors is in units of
512 byte blocks, on a 4k sector disk, every time we went through
sd_revalidate_disk, we were taking the current value of
queue_max_hw_sectors and increasing it by a factor of 8. Fix
this by only shifting sdkp->max_xfer_blocks.

[PATCH 3.18 10/39] MIPS: Fix C0_Pagegrain[IEC] support.

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Daney <david.daney@cavium.com>

commit 9ead8632bbf454cfc709b6205dc9cd8582fb0d64 upstream.

The following commits:

  5890f70f15c52d (MIPS: Use dedicated exception handler if CPU supports RI/XI exceptions)
  6575b1d4173eae (MIPS: kernel: cpu-probe: Detect unique RI/XI exceptions)

break the kernel for *all* existing MIPS CPUs that implement the
CP0_PageGrain[IEC] bit.  They cause the TLB exception handlers to be
generated without the legacy execute-inhibit handling, but never set
the CP0_PageGrain[IEC] bit to activate the use of dedicated exception
vectors for execute-inhibit exceptions.  The result is that upon
detection of an execute-inhibit violation, we loop forever in the TLB
exception handlers instead of sending SIGSEGV to the task.

If we are generating TLB exception handlers expecting separate
vectors, we must also enable the CP0_PageGrain[IEC] feature.

The bug was introduced in kernel version 3.17.

[PATCH 3.18 11/39] MIPS: IRQ: Fix disable_irq on CPU IRQs

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd@openwrt.org>

commit a3e6c1eff54878506b2dddcc202df9cc8180facb upstream.

If the irq_chip does not define .irq_disable, any call to disable_irq
will defer disabling the IRQ until it fires while marked as disabled.
This assumes that the handler function checks for this condition, which
handle_percpu_irq does not. In this case, calling disable_irq leads to
an IRQ storm, if the interrupt fires while disabled.

This optimization is only useful when disabling the IRQ is slow, which
is not true for the MIPS CPU IRQ.

Disable this optimization by implementing .irq_disable and .irq_enable

[PATCH 3.18 12/39] MIPS: OCTEON: fix kernel crash when offlining a CPU

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

From: Aaro Koskinen <aaro.koskinen@iki.fi>

commit 63a87fe0d0de2ce126a8cec9a299a133cfd5658e upstream.

octeon_cpu_disable() will unconditionally enable interrupts when called.
We can assume that the routine is always called with interrupts disabled,
so just delete the incorrect local_irq_disable/enable().

The patch fixes the following crash when offlining a CPU:

[PATCH 3.18 13/39] MIPS: Fix kernel lockup or crash after CPU offline/online

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hemmo Nieminen <hemmo.nieminen@iki.fi>

commit c7754e75100ed5e3068ac5085747f2bfc386c8d6 upstream.

As printk() invocation can cause e.g. a TLB miss, printk() cannot be
called before the exception handlers have been properly initialized.
This can happen e.g. when netconsole has been loaded as a kernel module
and the TLB table has been cleared when a CPU was offline.

Call cpu_report() in start_secondary() only after the exception handlers
have been initialized to fix this.

Without the patch the kernel will randomly either lockup or crash
after a CPU is onlined and the console driver is a module.

[PATCH 3.18 14/39] MIPS: mipsregs.h: Add write_32bit_cp1_register()

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Hogan <james.hogan@imgtec.com>

commit 5e32033e14ca9c7f7341cb383f5a05699b0b5382 upstream.

Add a write_32bit_cp1_register() macro to compliment the
read_32bit_cp1_register() macro. This is to abstract whether .set
hardfloat needs to be used based on GAS_HAS_SET_HARDFLOAT.

The implementation of _read_32bit_cp1_register() .sets mips1 due to
failure of gas v2.19 to assemble cfc1 for Octeon (see commit
25c300030016 ("MIPS: Override assembler target architecture for
octeon.")). I haven't copied this over to _write_32bit_cp1_register() as
I'm uncertain whether it applies to ctc1 too, or whether anybody cares
about that version of binutils any longer.

[PATCH 3.18 15/39] MIPS: traps: Fix inline asm ctc1 missing .set hardfloat

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Hogan <james.hogan@imgtec.com>

commit d76e9b9fc5de7e8fc4fd0e72a94e8c723929ffea upstream.

Commit 842dfc11ea9a ("MIPS: Fix build with binutils 2.24.51+") in v3.18
enabled -msoft-float and sprinkled ".set hardfloat" where necessary to
use FP instructions. However it missed enable_restore_fp_context() which
since v3.17 does a ctc1 with inline assembly, causing the following
assembler errors on Mentor's 2014.05 toolchain:

{standard input}: Assembler messages:
{standard input}:2913: Error: opcode not supported on this processor: mips32r2 (mips32r2) `ctc1 $2,$31'
scripts/Makefile.build:257: recipe for target 'arch/mips/kernel/traps.o' failed

Fix that to use the new write_32bit_cp1_register() macro so that ".set
hardfloat" is automatically added when -msoft-float is in use.

[PATCH 3.18 16/39] ARM: 8299/1: mm: ensure local active ASID is marked as allocated on rollover

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Will Deacon <will.deacon@arm.com>

commit 8e64806672466392acf19e14427d1c29df3e58b9 upstream.

Commit e1a5848e3398 ("ARM: 7924/1: mm: don't bother with reserved ttbr0
when running with LPAE") removed the use of the reserved TTBR0 value
for LPAE systems, since the ASID is held in the TTBR and can be updated
atomicly with the pgd of the next mm.

Unfortunately, this patch forgot to update flush_context, which
deliberately avoids marking the local active ASID as allocated, since we
used to switch via ASID zero and didn't need to allocate the ASID of
the previous mm. The side-effect of this is that we can allocate the
same ASID to the next mm and, between flushing the local TLB and updating
TTBR0, we can perform speculative TLB fills for userspace nG mappings
using the page table of the previous mm.

The consequence of this is that the next mm can erroneously hit some
mappings of the previous mm. Note that this was made significantly
harder to hit by a391263cd84e ("ARM: 8203/1: mm: try to re-use old ASID
assignments following a rollover") but is still theoretically possible.

This patch fixes the problem by removing the code from flush_context
that forces the allocated ASID to zero for the local CPU. Many thanks
to the Broadcom guys for tracking this one down.

[PATCH 3.18 17/39] Complete oplock break jobs before closing file handle

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sachin Prabhu <sprabhu@redhat.com>

commit ca7df8e0bb2a5ec79691de8a1a4c0e611fe04e60 upstream.

Commit
c11f1df5003d534fd067f0168bfad7befffb3b5c
requires writers to wait for any pending oplock break handler to
complete before proceeding to write. This is done by waiting on bit
CIFS_INODE_PENDING_OPLOCK_BREAK in cifsFileInfo->flags. This bit is
cleared by the oplock break handler job queued on the workqueue once it
has completed handling the oplock break allowing writers to proceed with
writing to the file.

While testing, it was noticed that the filehandle could be closed while
there is a pending oplock break which results in the oplock break
handler on the cifsiod workqueue being cancelled before it has had a
chance to execute and clear the CIFS_INODE_PENDING_OPLOCK_BREAK bit.
Any subsequent attempt to write to this file hangs waiting for the
CIFS_INODE_PENDING_OPLOCK_BREAK bit to be cleared.

We fix this by ensuring that we also clear the bit
CIFS_INODE_PENDING_OPLOCK_BREAK when we remove the oplock break handler
from the workqueue.

The bug was found by Red Hat QA while testing using ltp's fsstress
command.

[PATCH 3.18 18/39] md/raid5: fix another livelock caused by non-aligned writes.

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: NeilBrown <neilb@suse.de>

commit b1b02fe97f75b12ab34b2303bfd4e3526d903a58 upstream.

If a non-page-aligned write is destined for a device which
is missing/faulty, we can deadlock.

As the target device is missing, a read-modify-write cycle
is not possible.
As the write is not for a full-page, a recontruct-write cycle
is not possible.

This should be handled by logic in fetch_block() which notices
there is a non-R5_OVERWRITE write to a missing device, and so
loads all blocks.

However since commit 67f455486d2ea2, that code requires
STRIPE_PREREAD_ACTIVE before it will active, and those circumstances
never set STRIPE_PREREAD_ACTIVE.

So: in handle_stripe_dirtying, if neither rmw or rcw was possible,
set STRIPE_DELAYED, which will cause STRIPE_PREREAD_ACTIVE be set
after a suitable delay.

[PATCH 3.18 19/39] mm: pagewalk: call pte_hole() for VM_PFNMAP during walk_page_range

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shiraz Hashim <shashim@codeaurora.org>

commit 23aaed6659df9adfabe9c583e67a36b54e21df46 upstream.

walk_page_range() silently skips vma having VM_PFNMAP set, which leads
to undesirable behaviour at client end (who called walk_page_range).
Userspace applications get the wrong data, so the effect is like just
confusing users (if the applications just display the data) or sometimes
killing the processes (if the applications do something with
misunderstanding virtual addresses due to the wrong data.)

For example for pagemap_read, when no callbacks are called against
VM_PFNMAP vma, pagemap_read may prepare pagemap data for next virtual
address range at wrong index.

Eventually userspace may get wrong pagemap data for a task.
Corresponding to a VM_PFNMAP marked vma region, kernel may report
mappings from subsequent vma regions.  User space in turn may account
more pages (than really are) to the task.

In my case I was using procmem, procrack (Android utility) which uses
pagemap interface to account RSS pages of a task.  Due to this bug it
was giving a wrong picture for vmas (with VM_PFNMAP set).

[PATCH 3.18 21/39] memcg, shmem: fix shmem migration to use lrucare

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michal Hocko <mhocko@suse.cz>

commit f5e03a4989e80a86f8b514659dca8539132e6e09 upstream.

It has been reported that 965GM might trigger

  VM_BUG_ON_PAGE(!lrucare && PageLRU(oldpage), oldpage)

in mem_cgroup_migrate when shmem wants to replace a swap cache page
because of shmem_should_replace_page (the page is allocated from an
inappropriate zone).  shmem_replace_page expects that the oldpage is not
on LRU list and calls mem_cgroup_migrate without lrucare.  This is
obviously incorrect because swapcache pages might be on the LRU list
(e.g. swapin readahead page).

Fix this by enabling lrucare for the migration in shmem_replace_page.
Also clarify that lrucare should be used even if one of the pages might
be on LRU list.

The BUG_ON will trigger only when CONFIG_DEBUG_VM is enabled but even
without that the migration code might leave the old page on an
inappropriate memcg' LRU which is not that critical because the page
would get removed with its last reference but it is still confusing.

[PATCH 3.18 22/39] nilfs2: fix deadlock of segment constructor over I_SYNC flag

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

commit 7ef3ff2fea8bf5e4a21cef47ad87710a3d0fdb52 upstream.

Nilfs2 eventually hangs in a stress test with fsstress program.  This
issue was caused by the following deadlock over I_SYNC flag between
nilfs_segctor_thread() and writeback_sb_inodes():

  nilfs_segctor_thread()
    nilfs_segctor_thread_construct()
      nilfs_segctor_unlock()
        nilfs_dispose_list()
          iput()
            iput_final()
              evict()
                inode_wait_for_writeback()  * wait for I_SYNC flag

  writeback_sb_inodes()
     * set I_SYNC flag on inode->i_state
    __writeback_single_inode()
      do_writepages()
        nilfs_writepages()
          nilfs_construct_dsync_segment()
            nilfs_segctor_sync()
               * wait for completion of segment constructor
    inode_sync_complete()
       * clear I_SYNC flag after __writeback_single_inode() completed

writeback_sb_inodes() calls do_writepages() for dirty inodes after
setting I_SYNC flag on inode->i_state.  do_writepages() in turn calls
nilfs_writepages(), which can run segment constructor and wait for its
completion.  On the other hand, segment constructor calls iput(), which
can call evict() and wait for the I_SYNC flag on
inode_wait_for_writeback().

Since segment constructor doesn't know when I_SYNC will be set, it
cannot know whether iput() will block or not unless inode->i_nlink has a
non-zero count.  We can prevent evict() from being called in iput() by
implementing sop->drop_inode(), but it's not preferable to leave inodes
with i_nlink == 0 for long periods because it even defers file
truncation and inode deallocation.  So, this instead resolves the
deadlock by calling iput() asynchronously with a workqueue for inodes
with i_nlink == 0.

[PATCH 3.18 23/39] drm/radeon: dont init gpuvm if accel is disabled (v3)

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

commit 544143f9e01a60a93eb00ab4bfcb9bf4702a2a7d upstream.

If acceleration is disabled, it does not make sense
to init gpuvm since nothing will use it.  Moreover,
if radeon_vm_init() gets called it uses accel to try
and clear the pde tables, etc. which results in a bug.

v2: handle vm_fini as well
v3: handle bo_open/close as well

Bug:

commit a124d068bf5be6be2ff4b9fab77b1b7509107e68 upstream.

Should be the same as cayman.  We don't use VM by default
on NI parts so this isn't critical.

[PATCH 3.18 29/39] arm64: Fix up /proc/cpuinfo

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Rutland <mark.rutland@arm.com>

commit 44b82b7700d05a52cd983799d3ecde1a976b3bed upstream.

Commit d7a49086f263164a (arm64: cpuinfo: print info for all CPUs)
attempted to clean up /proc/cpuinfo, but due to concerns regarding
further changes was reverted in commit 5e39977edf6500fd (Revert "arm64:
cpuinfo: print info for all CPUs").

There are two major issues with the arm64 /proc/cpuinfo format
currently:

* The "Features" line describes (only) the 64-bit hwcaps, which is
  problematic for some 32-bit applications which attempt to parse it. As
  the same names are used for analogous ISA features (e.g. aes) despite
  these generally being architecturally unrelated, it is not possible to
  simply append the 64-bit and 32-bit hwcaps in a manner that might not
  be misleading to some applications.

  Various potential solutions have appeared in vendor kernels. Typically
  the format of the Features line varies depending on whether the task
  is 32-bit.

* Information is only printed regarding a single CPU. This does not
  match the ARM format, and does not provide sufficient information in
  big.LITTLE systems where CPUs are heterogeneous. The CPU information
  printed is queried from the current CPU's registers, which is racy
  w.r.t. cross-cpu migration.

This patch attempts to solve these issues. The following changes are
made:

* When a task with a LINUX32 personality attempts to read /proc/cpuinfo,
  the "Features" line contains the decoded 32-bit hwcaps, as with the
  arm port. Otherwise, the decoded 64-bit hwcaps are shown. This aligns
  with the behaviour of COMPAT_UTS_MACHINE and COMPAT_ELF_PLATFORM. In
  the absense of compat support, the Features line is empty.

  The set of hwcaps injected into a task's auxval are unaffected.

* Properties are printed per-cpu, as with the ARM port. The per-cpu
  information is queried from pre-recorded cpu information (as used by
  the sanity checks).

* As with the previous attempt at fixing up /proc/cpuinfo, the hardware
  field is removed. The only users so far are 32-bit applications tied
  to particular boards, so no portable applications should be affected,
  and this should prevent future tying to particular boards.

The following differences remain:

* No model_name is printed, as this cannot be queried from the hardware
  and cannot be provided in a stable fashion. Use of the CPU
  {implementor,variant,part,revision} fields is sufficient to identify a
  CPU and is portable across arm and arm64.

* The following system-wide properties are not provided, as they are not
  possible to provide generally. Programs relying on these are already
  tied to particular (32-bit only) boards:
  - Hardware
  - Revision
  - Serial

No software has yet been identified for which these remaining
differences are problematic.

[PATCH 3.18 32/39] ASoC: sgtl5000: add delay before first I2C access

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Nelson <eric.nelson@boundarydevices.com>

commit 58cc9c9a175885bbf6bae3acf18233d0a8229a84 upstream.

To quote from section 1.3.1 of the data sheet:
	The SGTL5000 has an internal reset that is deasserted
	8 SYS_MCLK cycles after all power rails have been brought
	up. After this time, communication can start

	...
	1.0us represents 8 SYS_MCLK cycles at the minimum 8.0 MHz SYS_MCLK.

[PATCH 3.18 33/39] ALSA: ak411x: Fix stall in work callback

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit 4161b4505f1690358ac0a9ee59845a7887336b21 upstream.

When ak4114 work calls its callback and the callback invokes
ak4114_reinit(), it stalls due to flush_delayed_work().  For avoiding
this, control the reentrance by introducing a refcount.  Also
flush_delayed_work() is replaced with cancel_delayed_work_sync().

The exactly same bug is present in ak4113.c and fixed as well.

[PATCH 3.18 35/39] x86, microcode: Return error from driver init code when loader is disabled

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Ostrovsky <boris.ostrovsky@oracle.com>

commit da63865a01c6384d459464e5165d95d4f04878d8 upstream.

Commits 65cef1311d5d ("x86, microcode: Add a disable chicken bit") and
a18a0f6850d4 ("x86, microcode: Don't initialize microcode code on
paravirt") allow microcode driver skip initialization when microcode
loading is not permitted.

However, they don't prevent the driver from being loaded since the
init code returns 0. If at some point later the driver gets unloaded
this will result in an oops while trying to deregister the (never
registered) device.

To avoid this, make init code return an error on paravirt or when
microcode loading is disabled. The driver will then never be loaded.

[PATCH 3.18 36/39] smpboot: Add missing get_online_cpus() in smpboot_register_percpu_thread()

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lai Jiangshan <laijs@cn.fujitsu.com>

commit 4bee96860a65c3a62d332edac331b3cf936ba3ad upstream.

The following race exists in the smpboot percpu threads management:

CPU0	      	   	     CPU1
cpu_up(2)
  get_online_cpus();
  smpboot_create_threads(2);
			     smpboot_register_percpu_thread();
			     for_each_online_cpu();
			       __smpboot_create_thread();
  __cpu_up(2);

This results in a missing per cpu thread for the newly onlined cpu2 and
in a NULL pointer dereference on a consecutive offline of that cpu.

Proctect smpboot_register_percpu_thread() with get_online_cpus() to
prevent that.

[ tglx: Massaged changelog and removed the change in
        smpboot_unregister_percpu_thread() because that's an
        optimization and therefor not stable material. ]

[PATCH 3.18 37/39] hrtimer: Fix incorrect tai offset calculation for non high-res timer systems

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: John Stultz <john.stultz@linaro.org>

commit 2d926c15d629a13914ce3e5f26354f6a0ac99e70 upstream.

I noticed some CLOCK_TAI timer test failures on one of my
less-frequently used configurations. And after digging in I
found in 76f4108892d9 (Cleanup hrtimer accessors to the
timekepeing state), the hrtimer_get_softirq_time tai offset
calucation was incorrectly rewritten, as the tai offset we
return shold be from CLOCK_MONOTONIC, and not CLOCK_REALTIME.

This results in CLOCK_TAI timers expiring early on non-highres
capable machines.

This patch fixes the issue, calculating the tai time properly
from the monotonic base.

[PATCH 3.18 38/39] tracing: Add condition check to RCU lockdep checks

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

commit a05d59a5673339ef6936d6940cdf68172ce75b9f upstream.

The trace_tlb_flush() tracepoint can be called when a CPU is going offline.
When a CPU is offline, RCU is no longer watching that CPU and since the
tracepoint is protected by RCU, it must not be called. To prevent the
tlb_flush tracepoint from being called when the CPU is offline, it was
converted to a TRACE_EVENT_CONDITION where the condition checks if the
CPU is online before calling the tracepoint.

Unfortunately, this was not enough to stop lockdep from complaining about
it. Even though the RCU protected code of the tracepoint will never be
called, the condition is hidden within the tracepoint, and even though the
condition prevents RCU code from being called, the lockdep checks are
outside the tracepoint (this is to test tracepoints even when they are not
enabled).

Even though tracepoints should be checked to be RCU safe when they are not
enabled, the condition should still be considered when checking RCU.

[PATCH 3.18 39/39] x86/tlb/trace: Do not trace on CPU that is offline

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

commit 6c8465a82a605bc692304bab42703017dcfff013 upstream.

When taking a CPU down for suspend and resume, a tracepoint may be called
when the CPU has been designated offline. As tracepoints require RCU for
protection, they must not be called if the current CPU is offline.

Unfortunately, trace_tlb_flush() is called in this scenario as was noted
by LOCKDEP:

Compiled and booted on my test system.

I am seeing the following mei_me messages:

mei_me 0000:00:16.0: version message write failed: ret = -5
mei_me 0000:00:16.0: hbm_start failed ret = -5
mei_me 0000:00:16.0: version message write failed: ret = -5
mei_me 0000:00:16.0: hbm_start failed ret = -5

Not concerned - maybe Alexander Usyskin and Tomas Winkler
can take a look and see if this looks ok.

Could this be related to:

mei: clean reset bit before reset

commit b13a65ef190e488e2761d65bdd2e1fe8a3a125f5 upstream.

Odd, I wouldn't think that this commit would cause those errors to show
up, if so, that's not good.

Alexander, any thoughts?

mei_hbm_reset() is called just before the above message. Maybe the reset is not
complete ? The comment associated with the commit suggests that this can happen.
If so, there should also be warning "H_RST is set = 0x%08X" in the log.

Can you please provide details of your system + lspci -vn output 
The complete log would helpful and if you can enable dynamic debug on mei and mei_me modules it would be the best.

Hi Tomas,

Please see attached dmidecode output, the original dmesg from when
I saw the problem, and dmesg after enabling dynamic debug on mei.
I can't reproduce the problem with dynamic debug enabled, tried a
couple of reboots.

Please let me know you need more information.

thanks,
-- Shuah
