There are two code paths how page with pmd page table can be freed:
pmd_free() and pmd_free_tlb().I've missed the second one and didn't add page table destructor call
there. It leads to leak of page->ptl for pmd page tables, if
dynamically allocated page->ptl is in use.The patch adds the missed destructor and modifies documentation
accordingly.Signed-off-by: Kirill A. Shutemov

…rm-intel into drm-fixes
Just a small pile of fixes for bugs and a few regressions. I'm still
trying to track down a driver load hang on my g33 (which infuriatingly
doesn't happen when loading the module manually after boot), somehow
bisecting loves to go astray on this one :( And there's a (harmless)

The VSX MSR bit in the user context indicates if the context contains VSX
state. Currently we set this when the process has touched VSX at any stage.Unfortunately, if the user has not provided enough space to save the VSX state,
we can't save it but we currently still set the MSR VSX bit.This patch changes this to clear the MSR VSX bit when the user doesn't provide
enough space. This indicates that there is no valid VSX state in the user
context.This is needed to support get/set/make/swapcontext for applications that use
VSX but only provide a small context. For example, getcontext in glibc
provides a smaller context since the VSX registers don't need to be saved over
the glibc function call. But since the program calling getcontext may have
used VSX, the kernel currently says the VSX state is valid when it's not. If
the returned context is then used in setcontext (ie. a small context without
VSX but with MSR VSX set), the kernel will refuse the context. This situation
has been reported by the glibc community.Based on patch from Carlos O'Donell.

In commit a489043 "Implement arch_get_random_long() based on H_RANDOM" I
broke the SMP=n build. We were getting plpar_wrappers.h via spinlock.h

Up until now we have only used cpu_to_chip_id() in the topology code,
which is only used on SMP builds. However my recent commit a4da0d5
"Implement arch_get_random_long/int() for powernv" added a usage when
SMP=n, breaking the build.Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds.
We would move the extern to prom.h, but that breaks the include in
topology.h. Instead we leave it in smp.h, but move it out of the
CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because
the linux version skips asm/smp.h on UP. What a mess.Signed-off-by: Michael Ellerman

I encountered following issue:
[ 0.283035] ibmvscsi 30000015: couldn't initialize event pool
[ 5.688822] ibmvscsi: probe of 30000015 failed with error -1which prevents the storage from being recognized, and the machine from
booting.After some digging, it seems that it is caused by commit 4886c399da
as dma_mask pointer in viodev->dev is not set, so in
dma_set_mask_and_coherent(), dma_set_coherent_mask() is not called
because dma_set_mask(), which is dma_set_mask_pSeriesLP() returned EIO.
While before the commit, dma_set_coherent_mask() is always called.I tried to replace dma_set_mask_and_coherent() with
dma_coerce_mask_and_coherent(), and the machine could boot again.Signed-off-by: Benjamin Herrenschmidt

Commit fba2369e6ceb (mm: use vm_unmapped_area() on powerpc architecture)
has a bug in slice_scan_available() where we compare an unsigned long
(high_slices) against a shifted int. As a result, comparisons against
the top 32 bits of high_slices (representing the top 32TB) always
returns 0 and the top of our mmap region is clamped at 32TBThis also breaks mmap randomisation since the randomised address is
always up near the top of the address space and it gets clamped down
to 32TB.Cc: stable@vger.kernel.org # v3.10+

H_SET_MODE and finally adds a kconfig option and defconfig.ABIv2 support was recently committed to binutils and gcc, and should

I've finally tracked down why my CR signal-unwind test case still
fails on little-endian. The problem turned to be that the kernel
installs a signal trampoline in the vDSO, and provides a DWARF CFI
record for that trampoline. This CFI describes the save location
for CR:rsave (70, 38*RSIZE + (RSIZE - CRSIZE))
which is correct for big-endian, but points to the wrong word on
little-endian. This is wrong no matter which ABI.In addition, for the ELFv2 ABI, we should not only provide a CFI
record for register 70 (cr2), but for all CR fields separately.
Strictly speaking, I guess this would mean providing two separate
vDSO images, one for ELFv1 processes and one for ELFv2 processes (or
maybe playing some tricks with conditional DWARF expressions).
However, having CFI records for the other CR fields in ELFv1 is not
actually wrong, they just will be ignored. So it seems the simplest
fix would be just to always provide CFI for all the fields.Signed-off-by: Ulrich Weigand
