There is some inconsistency between architectures about where exactly

The traditional place is in system.h but the more logical point for it
is in atomic.h - where most architectures (especially new ones) have
it defined. These architecture also still offer it via system.h.
Some, such as Sparc or s390 only have it in asm/system.h and not available

edac: use to_delayed_work()
The edac-core driver includes code which assumes that the work_struct
which is included in every delayed_work is the first member of that

use to_delayed_work() instead, which doesn't make such an assumption.

ext2: fix data corruption for racing writes
If two writers allocating blocks to file race with each other (e.g.
because writepages races with ordinary write or two writepages race with
each other), ext2_getblock() can be called on the same inode in parallel.
Before we are going to allocate new blocks, we have to recheck the block
chain we have obtained so far without holding truncate_mutex. Otherwise
we could overwrite the indirect block pointer set by the other writer
leading to data loss.
The below test program by Ying is able to reproduce the data loss with ext2
on in BRD in a few minutes if the machine is under memory pressure:
long kMemSize = 50 << 20;
int kPageSize = 4096;
int main(int argc, char **argv) {
int status;
int count = 0;
int i;
char *fname = "/mnt/test.mmap";
char *mem;
unlink(fname);
int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600);
status = ftruncate(fd, kMemSize);
mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
// Fill the memory with 1s.
memset(mem, 1, kMemSize);
sleep(2);
for (i = 0; i < kMemSize; i++) {
int byte_good = mem[i] != 0;
if (!byte_good && ((i % kPageSize) == 0)) {
//printf("%d ", i / kPageSize);
count++;

shmem: respect MAX_LFS_FILESIZE
SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect

Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to
grow slightly bigger than that supposed maximum.
Fix this by using the min of both (at build time not run time). And it
happens that this calculation is good as far as 8MB pages on 32-bit or
16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that,
it's truncated to such large numbers that we don't need to care.

With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large

from 'unsigned long' to 'unsigned long long'.
Hugh: reverted its unsigned long longs in shmem_truncate_range() and

initramfs: fix initramfs to work with hardlinked init
Change
cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on
initramfs") seems to have broken booting from initramfs with /sbin/init
being a hardlink.
It seems like the logic required for XIP on nommu, i.e. ftruncate to
reported cpio header file size (body_len) is broken for hardlinks, which
have a reported size of 0, and the truncate thus nukes the contents of the
file (in my case busybox), making boot impossible and ending with runaway
loop modprobe binfmt-0000 - and of course 0000 is not a valid binary
format.
My fix is to only call ftruncate if size is non-zero which fixes things
for me, but I'm not certain whether this will break XIP for those files on
nommu systems, although I would guess not.

Since that patch we have a window after exit_ptrace() drops tasklist and
before forget_original_parent() takes it again. In this window the child
can do ptrace(PTRACE_TRACEME) and nobody can untrace this child after

Change ptrace_traceme() to not attach to the exiting ->real_parent. We

sa1100fb: fix color component length for pseudocolor modes
sa1100fb incorrectly sets the length of the color fields to 8 bits for
PSEUDOCOLOR modes for which only 4 bits are used per pixel. Fix this by

hfs: fix memory leak when unmounting
When an HFS filesystem is unmounted, it leaks a 2-page bitmap. Also,
under extreme memory pressure, it's possible that hfs_releasepage() may
use a tree pointer that has not been initialized, and if so, the release
request should just be rejected.

hwmon: sht15 humidity sensor driver
Data sheet at:
http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf
These sensors communicate over a 2 wire bus running a device specific
protocol. The complexity of the driver is mainly due to handling the
substantial delays between requesting a reading and the device pulling the
data line low to indicate that the data is available. This is handled by
an interrupt that is disabled under all other conditions.
I wasn't terribly clear on the best way to handle this, so comments on
that aspect would be particularly welcome!
Interpretation of the temperature depends on knowing the supply voltage.
If configured in a board config as a regulator consumer this is obtained
from the regulator subsystem. If not it should be provided in the
platform data.
I've placed this driver in the hwmon subsystem as it is definitely a
device that may be used for hardware monitoring and with it's relatively
slow response times (up to 120 millisecs to get a reading) a caching
strategy certainly seems to make sense!
