Make rd_size static because it is local to drivers/block/brd.c
This was reported by sparse:
drivers/block/brd.c:445:5: warning: symbol 'rd_size' was not declared.
Should it be static?

Update the annotation for the kaddr pointer returned by direct_access()
so that it is a __pmem pointer. This is consistent with the PMEM driver
and with how this direct_access() pointer is used in the DAX code.

Move the x86 PMEM API implementation out of asm/cacheflush.h and into
its own header asm/pmem.h. This will allow members of the PMEM API to
be more easily identified on this and other architectures.

The goal of this series is to enhance the DAX I/O path so that all operations
that store data (I/O writes, zeroing blocks, punching holes, etc.) properly
synchronize the stores to media using the PMEM API. This ensures that the data

Well, I certainly don't disagree, but at the same time I suspect that
(a) many distros will not update glibc very aggressively and (b) we
should fix the unnecessarily expensive kernel

Hi James,
Can you pull this into security/next please? Its aim is twofold: firstly,

We are going to rework how compound_head() work. It will not use
page->first_page as we have it now.
The only other user of page->fisrt_page beyond compound pages is
zsmalloc.
Let's use page->private instead of page->first_page here. It occupies
the same storage space.
Signed-off-by: Kirill A.
Here's my attempt on fixing recently discovered race in compound_head().
It should make compound_head() reliable in all contexts.
The patchset is against Linus' tree. Let me know if it need to be rebased
onto different baseline.
It's expected to have conflicts with my page-flags patchset and
Hugh has pointed that compound_head() call can be unsafe in some
context. There's one example:

isolate_migratepages_block()
page_count()

This gamepad advertise 5 absolute axis while 4 are actually used.
The second Z axis shows some garbage, so it has to be ignored by HID.
The first Z axis and the Rz one are actually Rx and Ry. Remap them.
We could also just remap and ignore the axis in .input_mapping(). I

The coherent DMA allocator works the same over all architectures supporting
dma_map operations.
This patch consolidates them and converges the minor differences:
- the debug_dma helpers are now called from all architectures, including
those that were previously missing them
-
Most architectures do not support non-coherent allocations and either
define dma_{alloc,free}_noncoherent to their coherent versions or stub
them out.
Openrisc uses dma_{alloc,free}_attrs to implement them, and only Mips
implements them directly.
This patch moves the Openrisc version to common
Almost everyone implements dma_set_mask the same way, although some time
that's hidden in ->set_dma_mask methods.
Move this implementation to common code, including a callout to override
the post-check action, and remove duplicate instaces in methods as well.
Unfortunately some architectures
Most architectures just call into ->dma_supported, but some also return 1
if the method is not present, or 0 if no dma ops are present (although
that should never happeb). Consolidate this more broad version into
common code.
Also fix h8300 which inorrectly always returned 0, which would have
Since 2009 we have a nice asm-generic header implementing lots of DMA API
functions for architectures using struct dma_map_ops, but unfortunately
it's still missing a lot of APIs that all architectures still have to
duplicate.
This series consolidates the remaining functions, although we still
Currently there are three valid implementations of dma_mapping_error:
(1) call ->mapping_error
(2) check for a hardcoded error code
(3) always return 0
This patch provides a common implementation that calls ->mapping_error
if present, then checks for DMA_ERROR_CODE if defined or otherwise

Since IRQ chip helpers were introduced drivers lose ability to
register separate lockdep classes for each registered GPIO IRQ
chip and the gpiolib now is using shared lockdep class for
all GPIO IRQ chips (gpiochip_irq_lock_class).
As result, lockdep will produce warning when there are min two

No need to read the typer register in the loop. Values do not change.
This patch is basically a prerequisite for a follow-on patch that adds
errata code for Cavium ThunderX. It moves the calculation of the
number of id entries to the beginning of the function close to other

This patch implements Cavium ThunderX erratum 23154.
The gicv3 of ThunderX requires a modified version for reading the IAR
status to ensure data synchronization. Since this is in the fast-path
and called with each interrupt, runtime patching is used using jump
label

Some root clock generators may have child branches that are controlled
by different CPUs. These RCGs require some special operations:
- some enable bits have to be toggled when we set the rate;
- if RCG is disabled we only cache the rate and set it later when enabled;
- when the RCG is
This patchset adds support for the iommu, gpu and audio clocks on
the MSM8916 platforms.
Changes since v2 (https://lkml.org/lkml/2015/6/5/324)
* Dropped patch for read-only RCGs as it is not needed.
* Updated RCGs with shared branches patch and addressed various issues
pointed by Stephen.

This implements two gicv3-its errata workarounds for ThunderX. Both
with small impact affecting only ITS table allocation.
erratum 22375: only alloc 8MB table size
erratum 24313: ignore memory access type
The fixes are in ITS initialization and basically ignore memory
Add support for the msm8916 audio clocks. This includes core bus,
low-power audio and codec clocks. They are required for audio playback.
