There is a bug in using ptrace to access FPRs via PTRACE_PEEKUSR /
PTRACE_POKEUSR. In effect, trying to access any of the FPRs always
really accesses FPR0, which does seriously break debugging :-)
The problem seems to have been introduced by commit 3ad26e5c44
(Merge branch 'for-kvm' into next).

The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are
too custom to be supported in a generic driver. Those clocks can be
divided in two categories:
- Fixed rate clocks with multiplier and divisor set according to boot
mode configuration
- Custom divider clocks with SoC-specific divider values
This driver supports both.

mm: memcg: do not declare OOM from __GFP_NOFAIL allocations
include/linux/hugetlb.h: make isolate_huge_page() an inline
Commit 4942642080 ("mm: memcg: handle non-error OOM situations more
gracefully") allowed tasks that already entered a memcg OOM condition to
bypass the memcg limit on subsequent allocation attempts hoping this
would expedite finishing the page fault and executing the kill.
David Rientjes is worried that this breaks memcg isolation guarantees
and since there is no evidence that the bypass actually speeds up fault
processing just change it so that these subsequent charge attempts fail
outright. The notable exception being __GFP_NOFAIL charges which are
required to bypass the limit regardless.

There is a race condition between a memcg being torn down and a swapin
triggered from a different memcg of a page that was recorded to belong
to the exiting memcg on swapout (with CONFIG_MEMCG_SWAP extension). The
result is unreclaimable pages pointing to dead memcgs, which can lead to
anything from endless loops in later memcg teardown (the page is charged
to all hierarchical parents but is not on any LRU list) or crashes from
following the dangling memcg pointer.
Memcgs with tasks in them can not be torn down and usually charges don't
show up in memcgs without tasks. Swapin with the CONFIG_MEMCG_SWAP
extension is the notable exception because it charges the cgroup that
was recorded as owner during swapout, which may be empty and in the
process of being torn down when a task in another memcg triggers the
swapin:
teardown: swapin:
lookup_swap_cgroup_id()
rcu_read_lock()
mem_cgroup_lookup()
css_tryget()
rcu_read_unlock()
disable css_tryget()
call_rcu()
offline_css()
reparent_charges()
res_counter_charge() (hierarchical!)
css_put()
css_free()
pc->mem_cgroup = dead memcg
add page to dead lru
Add a final reparenting step into css_free() to make sure any such raced
charges are moved out of the memcg before it's finally freed.
In the longer term it would be cleaner to have the css_tryget() and the
res_counter charge under the same RCU lock section so that the charge
reparenting is deferred until the last charge whose tryget succeeded is
visible. But this will require more invasive changes that will be
harder to evaluate and backport into stable, so better defer them to a
separate change set.

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.
On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC. This could be observed in various hangs,
e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Commit fad1a86e25 ("procfs: call default get_unmapped_area on
MMU-present architectures"), as its title says, took care of only the
MMU case, leaving the !MMU side still in the regressed state (returning
-EIO in all cases where pde->proc_fops->get_unmapped_area is NULL).
From the fad1a86e25 changelog:
"Commit c4fe244857 ("sparc: fix PCI device proc file mmap(2)") added
proc_reg_get_unmapped_area in proc_reg_file_ops and
proc_reg_file_ops_no_compat, by which now mmap always returns EIO if
get_unmapped_area method is not defined for the target procfs file, which
causes regression of mmap on /proc/vmcore.
To address this issue, like get_unmapped_area(), call default
current->mm->get_unmapped_area on MMU-present architectures if
pde->proc_fops->get_unmapped_area, i.e. the one in actual file operation
in the procfs file, is not defined"

Commit 84235de394 ("fs: buffer: move allocation failure loop into the

forgot to disable the OOM killer.
Any task that does not fail allocation will also not enter the OOM
completion path. So don't declare an OOM state in this case or it'll be
leaked and the task be able to bypass the limit until the next
userspace-triggered page fault cleans up the OOM state.

Instead of setting up pointers to memory locations in iop_format which then
get copied into the CIL linear buffer after return move the copy into
the individual inode items. This avoids the need to always have a memory
block in the exact same layout that gets written into the log around, and
allow the log items to be much more flexible in their in-memory layouts.
The only caveat is that we need to properly align the data for each
iovec so that don't have structures misaligned in subsequent iovecs.
Note that all log item format routines now need to be careful to modify
the copy of the item that was placed into the CIL after calls to
xlog_copy_iovec instead of the in-memory copy.

that fixes some longish-standing bugs around USB resets.
There are a couple of other changes that also add up line count a bit:
One is a long-standing bug with the keyboard layout on one of the
PXA platforms. The other is a fix for highbank that moves their
power-off/reset button handling to be done in-kernel since relying on
userspace to handle it was fragile and awkward.

Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"Another week, another batch of fixes.
Again, OMAP regressions due to move to DT is the bulk of the changes
here, but this should be the last of it for 3.13. There are also a
handful of OMAP hwmod changes (power management, reset handling) for
USB on OMAP3 that fixes some longish-standing bugs around USB resets.
There are a couple of other changes that also add up line count a bit:
One is a long-standing bug with the keyboard layout on one of the PXA
platforms. The other is a fix for highbank that moves their
power-off/reset button handling to be done in-kernel since relying on
userspace to handle it was fragile and awkward"

mtd: nand: pxa3xx: Allocate data buffer on detected flash size
the way the buffer is allocated was changed: the first READ_ID is issued
with a small kmalloc'ed buffer. Only once the flash page size is detected
the DMA buffers are allocated, and info->use_dma is set.
Currently, if the device detection fails, the driver checks the 'use_dma'
module parameter and tries to release unallocated DMA resources.
Fix this by checking the proper indicator of the DMA allocation, which
is 'info->use_dma'.

This partially reverts c0f3b8643a.
The "armada370-nand" compatible support is not complete, and it was mistake
to add it. Revert it and postpone the support until the infrastructure is
in place.
