Srikar Dronamraju reports that commit b0c29f79 ("futexes: Avoid
taking the hb->lock if there's nothing to wake up") causes java threads
getting stuck on futexes when runing specjbb on a power7 numa box.

The cause appears to be that the powerpc spinlocks aren't using the same
ticket lock model that we use on x86 (and other) architectures, which in
turn result in the "spin_is_locked()" test in hb_waiters_pending()
occasionally reporting an unlocked spinlock even when there are pending
waiters.

So this reinstates Davidlohr Bueso's original explicit waiter counting
code, which I had convinced Davidlohr to drop in favor of figuring out
the pending waiters by just using the existing state of the spinlock and
the wait queue.

Add remove_linear_migration_ptes_from_nonlinear(), to fix an interesting
little include/linux/swapops.h:131 BUG_ON(!PageLocked) found by trinity:
indicating that remove_migration_ptes() failed to find one of the
migration entries that was temporarily inserted.

The problem comes from remap_file_pages()'s switch from vma_interval_tree
(good for inserting the migration entry) to i_mmap_nonlinear list (no good
for locating it again); but can only be a problem if the remap_file_pages()
range does not cover the whole of the vma (zap_pte() clears the range).

remove_migration_ptes() needs a file_nonlinear method to go down the
i_mmap_nonlinear list, applying linear location to look for migration
entries in those vmas too, just in case there was this race.

The file_nonlinear method does need rmap_walk_control.arg to do this;
but it never needed vma passed in - vma comes from its own iteration.

In event format strings, the array size is reported in two locations.
One in array subscript and then via the "size:" attribute. The values
reported there have a mismatch.

For e.g., in sched:sched_switch the prev_comm and next_comm character
arrays have subscript values as [32] where as the actual field size is
16.

name: sched_switch
ID: 301

        field:unsigned short common_type;       offset:0;       size:2; signed:0;

92edca07 tracing: Use direct field, type and system names

This commit removes the duplication of strings for field->name and
field->type assuming that all the strings passed in
__trace_define_field() are immutable. This is not true for arrays, where
the type string is created in event_storage variable and field->type for
all array fields points to event_storage.

Use __stringify() to create a string constant for the type string.

Also, get rid of event_storage and event_storage_mutex that are not
needed anymore.

also, an added benefit is that this reduces the overhead of events a bit more:

For non-mipsr2 processors, the local_irq_disable contains an mfc0-mtc0
pair with instructions inbetween.  With preemption enabled, this sequence
may get preempted and effect a stale value of CP0_STATUS when executing
the mtc0 instruction.  This commit avoids this scenario by incrementing
the preempt count before the mfc0 and decrementing it after the mtc9.

With this commit the kernel starts mapping the interrupts listed for
gpio-controller node. irq_domain_ops for CIU (octeon_irq_ciu_map and
octeon_irq_ciu_xlat) refuse to handle the GPIO lines (returning -EINVAL)
and this is causing above warning in of_device_alloc().

Modify irq_domain_ops for CIU and CIU2 to "gracefully handle" GPIO
lines (neither return error code nor call octeon_irq_set_ciu_mapping
for it). This should avoid the warning.

(As before the real setup for GPIO lines will happen using
irq_domain_ops of gpio-controller.)

This reverts commit 56dd669a, which makes the GART visible in
/proc/iomem.  This fixes a regression: e501b3d8 ("agp: Support 64-bit
APBASE") exposed an existing problem with a conflict between the GART
region and a PCI BAR region.

The GART addresses are bus addresses, not CPU addresses, and therefore
should not be inserted in iomem_resource.

On many machines, the GART region is addressable by the CPU as well as by
an AGP master, but CPU addressability is not required by the spec.  On some
of these machines, the GART is mapped by a PCI BAR, and in that case, the
PCI core automatically inserts it into iomem_resource, just as it does for
all BARs.

Inserting it here means we'll have a conflict if the PCI core later tries
to claim the GART region, so let's drop the insertion here.

The conflict indirectly causes X failures, as reported by Jouni in the
bugzilla below.  We detected the conflict even before e501b3d8, but
after it the AGP code (fix_northbridge()) uses the PCI resource (which is
zeroed because of the conflict) instead of reading the BAR again.

Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull two 'perf bench' fixes from Arnaldo:

  * Make 'perf bench mem' (i.e. no args) mean 'run all tests' so that we can run
    all tests, not stopping at the numa ones.  (Arnaldo Carvalho de Melo)

  * Fix NULL pointer dereference after last test in in "perf bench all" (Patrick Palka)

If CONFIG_TRANSPARENT_HUGEPAGE is enabled, but CONFIG_HUGETLB_PAGE is not,
it is possible to end up with a configuration that fails to build with the
following error:

include/linux/huge_mm.h:125:2: error: #error "hugepages can't be allocated by the buddy allocator"

This is due to CONFIG_FORCE_MAX_ZONEORDER defaulting to 11. It already has
ranges that change the valid values when HUGETLB_PAGE is enabled, but this
is not done for TRANSPARENT_HUGEPAGE. Fix by changing the HUGETLB_PAGE
dependencies to MIPS_HUGE_TLB_SUPPORT, which includes both
TRANSPARENT_HUGEPAGE and HUGETLB_PAGE.

Commit 597ce172 "MIPS: Support for 64-bit FP with O32 binaries"
introduced support for setting Status.FR=1 for O32 binaries with the
EF_MIPS_FP64 ELF header flag set. Whilst this flag is currently
supported by binutils it does introduce an ABI break within userland.
Objects built with EF_MIPS_FP64 cannot be safely linked with those built
without it since code in either object may assume behaviour specific to
a value of FR.

More recently there has been discussion around avoiding further
fragmentation of the O32 ABI whilst still allowing the use of FR=1 and
features such as MSA which depend upon it. Details of the plan to allow
this are still being worked on, and whilst the kernel will need the
ability to handle FR=1 with O32 tasks it is unclear what else it may
need to provide to a userland which seeks to avoid another ABI break. In
order to prevent the proliferation of userland which may rely upon the
current EF_MIPS_FP64 behaviour this patch marks the kernel support for
it experimental & disables it by default. Under current proposals it is
likely that this support can simply be enabled again later, but possibly
after the introduction of further interfaces with userland and support
for the MIPS R5 UFR feature.

In 32-bit mode, the start address passed to flush_icache_range is
shifted by 4 bytes before the second safe_store_code() call.

This causes system crash from time to time because the first 4 bytes
might not be flushed properly. This bug exists since linux-3.8.

Also remove obsoleted comment while at it.

The syscall_get_arguments function expects the arguments to be copied
to the '*args' argument but instead a local variable was used to hold
the system call argument. As a result of which, this variable was
never passed to the filter and any filter testing the system call
arguments would fail. This is fixed by passing the '*args' variable
as the destination memory for the system call arguments.
