The tile tool chain uses the .eh_frame information for backtracing.
The vmlinux build drops any .eh_frame sections at link time, but when
present in kernel modules, it causes a module load failure due to the
presence of unsupported pc-relative relocations. When compiling to
use compiler feedback support, the compiler by default omits .eh_frame
information, so we don't see this problem. But when not using feedback,
we need to explicitly suppress the .eh_frame.

In theory, that function could release the lru lock between
checking for bo on ddestroy list and a successful reserve if the bo
was already reserved, and the function was called with waiting reserves
allowed.
However, all current reservers of a bo on the ddestroy list would
atomically take the bo off the list after a successful reserve so this
race should not have been hit, so no need to backport for stable.
This patch also fixes a case found by Maarten Lankhorst where
ttm_mem_evict_first called with no_wait_gpu would incorrectly

also sits on the ddestroy list.

This fixes a long-standing bug caused by the lack of separate COMM and EXEC
record types, which makes "perf report" lose track of symbols when a process
renames itself.
With this fix (suggested by Stephane Eranian), a COMM (rename) no longer
flushes the maps, which is the correct behavior. An EXEC also no longer
flushes the maps, but this doesn't matter because as new mappings are created
(for the executable and the libraries) the old mappings are automatically
removed. This is not by accident: the functionality is necessary because DLLs
can be explicitly loaded at any time with dlopen(), possibly on top of existing
text, so "perf report" handles correctly the clobbering of new mappings on top
of old ones.
An alternative patch (which I proposed earlier) would be to introduce a
separate PERF_RECORD_EXEC type, but it is a much larger change (about 300
lines) and is not necessary.

their respective structures representing input devices.
Unfortunately character device structure may outlive the parent
structure unless we do not set it up as parent of character device so
that it will stay pinned until character device is freed.
Also, now that parent structure is pinned while character device exists
we do not need to pin and unpin it every time user opens or closes it.

In certain cases (for example when a cdev structure is embedded into
another object whose lifetime is controlled by a separate kobject) it is
beneficial to tie lifetime of another object to the lifetime of
character device so that related object is not freed until after
char_dev object is freed.
To achieve this let's pin kobject's parent when doing cdev_add() and
unpin when last reference to cdev structure is being released.

In mke2fs, we only checksum the whole bitmap block and it is right.
While in the kernel, we use EXT4_BLOCKS_PER_GROUP to indicate the
size of the checksumed bitmap which is wrong when we enable bigalloc.
The right size should be EXT4_CLUSTERS_PER_GROUP and this patch fixes
it.
Also as every caller of ext4_block_bitmap_csum_set and
ext4_block_bitmap_csum_verify pass in EXT4_BLOCKS_PER_GROUP(sb)/8,
we'd better removes this parameter and sets it in the function itself.

Pull arm64 fixes from Catalin Marinas:
"Main changes:
- AArch64 Linux compilation fixes following 3.7-rc1 changes
(MODULES_USE_ELF_RELA, update_vsyscall() prototype)
- Unnecessary register setting in start_thread() (thanks to Al Viro)
- ptrace fixes"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64:
arm64: fix alignment padding in assembly code
arm64: ptrace: use HW_BREAKPOINT_EMPTY type for disabled breakpoints
arm64: ptrace: make structure padding explicit for debug registers
arm64: No need to set the x0-x2 registers in start_thread()
arm64: Ignore memory blocks below PHYS_OFFSET
arm64: Fix the update_vsyscall() prototype
arm64: Select MODULES_USE_ELF_RELA
arm64: Remove duplicate inclusion of mmu_context.h in smp.c
An interesting effect of using the generic version of linkage.h
is that the padding is defined in terms of x86 NOPs, which can have
even more interesting effects when the assembly code looks like this:
ENTRY(func1)
mov x0, xzr
ENDPROC(func1)
// fall through
ENTRY(func2)
mov x0, #1
ret
ENDPROC(func2)
Admittedly, the code is not very nice. But having code from another
architecture doesn't look completely sane either.
The fix is to add arm64's version of linkage.h, which causes the insertion
of proper AArch64 NOPs.

The min/max call needed to have explicit types on some architectures
(e.g. mn10300). Use clamp_t instead to avoid the warning:
kernel/sys.c: In function 'override_release':

. The python binding needs to link with libtraceevent and to initialize
the 'page_size' variable so that mmaping works again.
. The callchain folding character that appears on the TUI just before
the overhead had disappeared due to recent changes, add it back.
. Intel PEBS in VT-x context uses the DS address as a guest linear address,
even though its programmed by the host as a host linear address. This either
results in guest memory corruption and or the hardware faulting and 'crashing'
the virtual machine. Therefore we have to disable PEBS on VT-x enter and
re-enable on VT-x exit, enforcing a strict exclude_guest.
Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.
. Fix build on sparc due to UAPI, fix from David Miller.
. Fixes for the srclike sort key for unresolved symbols and when processing
samples in JITted code, where we don't have an ELF file, just an special
symbol table, fixes from Namhyung Kim.
. Fix some leaks in libtraceevent, from Steven Rostedt.

A set of fixes and some minor cleanups for -rc2:
- A series from Arnd that fixes warnings in drivers and other code
included by ARM defconfigs. Most have been acked by corresponding
maintainers (and seem quite hard to argue not picking up anyway in the
few exception cases).
- A few misc patches from the list for integrator/vt8500/i.MX
- A batch of fixes to OMAP platforms, fixing:
- boot problems on beaglebone,
- regression fixes for local timers
- clockdomain locking fixes
- a few boot/sparse warnings
- For Tegra:
- Clock rate calculation overflow fix
- Revert a change that removed timer clocks and a fix for symbol name clashes
- For Renesas:
- IO accessor / annotation cleanups to remove warnings
- For Kirkwood/Dove/mvebu:
- Fixes for device trees for Dove (some minor cleanups, some fixes)
- Fixes for the mvebu gpio driver
- Fix build problem for Feroceon due to missing ifdefs
- Fix lsxl DTS files
