ecryptfs_d_release() first dereferences a pointer (via
ecryptfs_dentry_to_lower()) and then afterwards checks to see if the
pointer it just dereferenced is NULL (via ecryptfs_dentry_to_private()).
This patch moves all of the work done on the dereferenced pointer inside a
block governed by the condition that the pointer is non-NULL.

hrtimer_forward() does not check for the possible overflow of
timer->expires. This can happen on 64 bit machines with large interval
values and results currently in an endless loop in the softirq because the
expiry value becomes negative and therefor the timer is expired all the
time.
Check for this condition and set the expiry value to the max. expiry time
in the future. The fix should be applied to stable kernel series as well.

It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ... among other things, it can be some time before
a driver is ready. This patch corrects that oversight, fixing
- documentation
- platforms supporting the GPIO interface
- users of that call (just one for now, others are pending)
There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.
Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ... so those chips might not avoid the glitches.

Fix a bug in the cleanup of an spi_bitbang bus.
The workqueue associated with the bus was destroyed before the call to
spi_unregister_master. That meant that spi devices on that bus would be
unable to do IO in their remove method. The shutdown flag should have been
able to prevent a segfault, but was never getting set. By waiting to
destroy the workqueue until after the master is unregistered, devices are
able to do IO in their remove methods. An added benefit is that neither
the shutdown flag nor a wait for the queue of messages to empty is needed.

This patch fixes a user-triggerable oops that was reported by Leonid
Ananiev as archived at http://lkml.org/lkml/2007/2/8/337.
dio writes invalidate clean pages that intersect the written region so that
subsequent buffered reads go to disk to read the new data. If this fails
the interface tries to tell the caller that the cache is inconsistent by
returning EIO.
Before this patch we had the problem where this invalidation failure would
clobber -EIOCBQUEUED as it made its way from fs/direct-io.c to fs/aio.c.
Both fs/aio.c and bio completion call aio_complete() and we reference freed
memory, usually oopsing.
This patch addresses this problem by invalidating before the write so that
we can cleanly return -EIO before ->direct_IO() has had a chance to return
-EIOCBQUEUED.
There is a compromise here. During the dio write we can fault in mmap()ed
pages which intersect the written range with get_user_pages() if the user
provided them for the source buffer. This is a crazy thing to do, but we
can make it mostly work in most cases by trying the invalidation again.
The compromise is that we won't return an error if this second invalidation
fails if it's an AIO write and we have -EIOCBQUEUED.
This was tested by having two processes race performing large O_DIRECT and
buffered ordered writes. Within minutes ext3 would see a race between
ext3_releasepage() and jbd holding a reference on ordered data buffers and
would cause invalidation to fail, panicing the box. The test can be found
in the 'aio_dio_bugs' test group in test.kernel.org/autotest. After this
patch the test passes.

This patch fix behaviour in such test scenario:
lseek(fd, BIG_OFFSET)
write(fd, buf, sizeof(buf))
truncate(BIG_OFFSET)
truncate(BIG_OFFSET + sizeof(buf))
read(fd, buf...)
Because of if file big enough(BIG_OFFSET) we start allocate space by block,
ordinary block size > page size, so we should zeroize the rest of block in
truncate(except last framgnet, about which VFS should care), to not get
garbage, when we extend file.
Also patch corrects conversion from pointer to block to physical block number,
this helps in case of not common used UFS types.
And add to debug output inode number.

This patch corrects work with time in UFS2 case.
1) According to UFS2 disk layout modification/access and so on "time"
should be hold in two variables one 64bit for seconds and another 32bit for
nanoseconds,
at now for some unknown reason we suppose that "inode time" holds in
three variables 32bit for seconds, 32bit for milliseconds and 32bit for
nanoseconds.
2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of
getting values from "on disk inode"(this should close
http://bugzilla.kernel.org/show_bug.cgi?id=7991).

This removes several pointless exports from drivers/dma/dmaengine.c; the
dma_async_memcpy_*() functions are inlined by <linux/dmaengine.h> so those
exports are inappropriate.
It also moves the existing EXPORT_SYMBOL declarations next to their functions,
so it's now trivial to confirm one-to-one correspondence between exports and
nonstatic symbols.

We have to make sure to use base-pagesize TLB entries even during the
early transition period where we need TLB miss handling but don't have
the kernel page tables setup yet for the linear region.
Also, it is necessary therefore to not use the 4MB TSB for these
translations, and instead use the normal kernel TSB. This allows us
to also get rid of the 4MB tsb for debug builds which shrinks the
kernel a little bit.

The ipv6_fl_socklist from listening socket is inadvertently shared
with new socket created for connection. This leads to a variety of
interesting, but fatal, bugs. For example, removing one of the
sockets may lead to the other socket's encountering a page fault
when the now freed list is referenced.
The fix is to not share the flow label list with the new socket.

From the HDA spec it appears that the buffers written to the BDL and
sent to a codec must be 128 byte aligned (section 4.5.1). The alignment
was not happening especially when playing 6 channels. This patch set
the alignment of buffers and periods to 128 bytes.

unregistration
This patch (as869) reinstates the mutual exclusion between sysfs
attribute method calls and attribute unregistration. The
previously-reported deadlocks have been fixed, and this exclusion is
by far the simplest way to avoid races during driver unbinding.
The check for orphaned read-buffers has been moved down slightly, so
that the remainder of a partially-read buffer will still be available
to userspace even after the attribute has been unregistered.

This patch (as868) adds a helper routine for device drivers that need
to set up a callback to perform some action in a different process's
context. This is intended for use by attribute methods that want to
unregister themselves or their parent device. Attribute method calls
are mutually exclusive with unregistration, so such actions cannot be
taken directly.
Two attribute methods are converted to use the new helper routine: one
for SCSI device deletion and one for System/390 ccwgroup devices.
