Documentation/printk-formats.txt says to use %zd for a ssize_t argument
and some drivers do. Unfortunately this prints a positive number for
negative values eg:
tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error 4294967234
Add a case to va_args a ssize_t type if the interpretation should be
signed.
Tested on PPC32.

The boot_delay parameter affects all printk(), even if the log level
prevents visible output from the call. It results in delays greater than
the user intended without purpose.
This patch changes the behaviour of boot_delay to only delay output.

The {in,out}s{b,w,l} functions are designed to operate on a stream of
bytes and therefore should not perform any byte-swapping, regardless of
the CPU byte order.
This patch fixes the generic IO header so that {in,out}s{b,w,l} call the
__raw_{read,write} functions directly rather than going via the
endian-correcting accessors.

Since userspace headers were moved to generated/uapi it possible to have a
stale copy of linux/version.h at that file's old location. This causes
confusion after building an older kernel version, then checking out and
building a new one; the old (stale) version header will still get picked
up until it is manually removed. This upsets the C library.
Since the uapi changes, include/linux/version.h is no longer generated and
should not be ignored, so this patch removes it from .gitignore.

Currently the __define_initcall() macro takes three arguments, fn, id and
level. The level argument is exactly the same as the id argument but
wrapped in quotes. To overcome this need to specify three arguments to
the __define_initcall macro, where one argument is the stringification of
another, we can just use the stringification macro instead.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
"While small this set of changes is very significant with respect to
containers in general and user namespaces in particular. The user
space interface is now complete.
This set of changes adds support for unprivileged users to create user
namespaces and as a user namespace root to create other namespaces.
The tyranny of supporting suid root preventing unprivileged users from
using cool new kernel features is broken.
This set of changes completes the work on setns, adding support for
the pid, user, mount namespaces.
This set of changes includes a bunch of basic pid namespace
cleanups/simplifications. Of particular significance is the rework of
the pid namespace cleanup so it no longer requires sending out
tendrils into all kinds of unexpected cleanup paths for operation. At
least one case of broken error handling is fixed by this cleanup.
The files under /proc/<pid>/ns/ have been converted from regular files
to magic symlinks which prevents incorrect caching by the VFS,
ensuring the files always refer to the namespace the process is
currently using and ensuring that the ptrace_mayaccess permission
checks are always applied.
The files under /proc/<pid>/ns/ have been given stable inode numbers
so it is now possible to see if different processes share the same
namespaces.
Through the David Miller's net tree are changes to relax many of the
permission checks in the networking stack to allowing the user
namespace root to usefully use the networking stack. Similar changes
for the mount namespace and the pid namespace are coming through my
tree.
Two small changes to add user namespace support were commited here adn
in David Miller's -net tree so that I could complete the work on the
/proc/<pid>/ns/ files in this tree.
Work remains to make it safe to build user namespaces and 9p, afs,
ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the
Kconfig guard remains in place preventing that user namespaces from
being built when any of those filesystems are enabled.
Future design work remains to allow root users outside of the initial
user namespace to mount more than just /proc and /sys."

Bug introduced in commit:
wireless: allow Atheros card to not depend on ath.ko
Commit in question changed CONFIG_ATH_COMMON to CONFIG_ATH_CARDS as
"Atheros card" indication in drivers/net/wireless/ath/Kconfig but it
is used also by drivers/net/wireless/Makefile
If there are only Atheros cards that do not require ATH_COMMON, whole
Makefile for Atheros cards was not executed; and as result, driver
won't compile in this case.
Change in CONFIG_ option name should be reflected in the
drivers/net/wireless/Makefile

In commit 'mac80211: support radiotap vendor namespace RX data'
new fields were added to 'struct ieee80211_rx_status' and those
fileds must be zeroed. However the rt2x00 driver stores driver
specific data in the cb array of the rx skbs, so the fields
might contain garbage and this can cause unexpected behaviour.
The rt2x00 driver from the compat-wireless-2012-12-01

The handling for directory crc hash overflows was fairly obscure,
split_leaf returns EOVERFLOW when we try to extend the item and that is
supposed to bubble up to userland. For a while it did so, but along the
way we added better handling of errors and forced the FS readonly if we
hit IO errors during the directory insertion.
Along the way, we started testing only for EEXIST and the EOVERFLOW case
was dropped. The end result is that we may force the FS readonly if we
catch a directory hash bucket overflow.
This fixes a few problem spots. First I add tests for EOVERFLOW in the
places where we can safely just return the error up the chain.
btrfs_rename is harder though, because it tries to insert the new
directory item only after it has already unlinked anything the rename
was going to overwrite. Rather than adding very complex logic, I added
a helper to test for the hash overflow case early while it is still safe
to bail out.
Snapshot and subvolume creation had a similar problem, so they are using
the new helper now too.

Pull DRM updates from Dave Airlie:
"This is the one and only next pull for 3.8, we had a regression we
found last week, so I was waiting for that to resolve itself, and I
ended up with some Intel fixes on top as well.
Highlights:
- new driver: nvidia tegra 20/30/hdmi support
- radeon: add support for previously unused DMA engines, more HDMI
regs, eviction speeds ups and fixes
- i915: HSW support enable, agp removal on GEN6, seqno wrapping
- exynos: IPP subsystem support (image post proc), HDMI
- nouveau: display class reworking, nv20->40 z compression
- ttm: start of locking fixes, rcu usage for lookups,
- core: documentation updates, docbook integration, monotonic clock
usage, move from connector to object properties"

!CONFIG_TRANSPARENT_HUGEPAGE
Michal Hocko reported that the following build error occurs if
CONFIG_NUMA_BALANCING is set without THP support
kernel/sched/fair.c: In function ‘task_numa_work’:
kernel/sched/fair.c:932:55: error: call to ‘__build_bug_failed’ declared with attribute error: BUILD_BUG failed
The problem is that HPAGE_PMD_SHIFT triggers a BUILD_BUG() on
!CONFIG_TRANSPARENT_HUGEPAGE. This patch addresses the problem.

This patch check difference value between current voltage of battery and
desc->fullbatt_uV whether positve or negative number. If difference value
is negative number when current voltage of battery is larger than
desc->fullbatt_uV, charger-manager return immediately because battery is
fully charged.

This patch fix bug related to checking fully charged state of battery when
charger-manager call is_full_charged() function. After reading property of
charger/fuel-gauge through power_supply API, val.intval is more than 1.
So, is_full_charged() function always return true. If true, battery means
fully charged state.

When a thread exits mix it's cputime (userspace + kernelspace) to the entropy pool.
We don't know how "random" this is, so we use add_device_randomness that doesn't mess
with entropy count.

Andrea's autonuma-benchmark numa01 hits kernel BUG at huge_memory.c:1474!
in change_huge_pmd called from change_protection from change_prot_numa
from task_numa_work.
That BUG, introduced in the huge zero page commit cad7f613c4d0 ("thp:
change_huge_pmd(): make sure we don't try to make a page writable")
was trying to verify that newprot never adds write permission to an
anonymous huge page; but Automatic NUMA Balancing's 4b10e7d562c9 ("mm:
mempolicy: Implement change_prot_numa() in terms of change_protection()")
adds a new prot_numa path into change_huge_pmd(), which makes no use of
the newprot provided, and may retain the write bit in the pmd.
Just move the BUG_ON(pmd_write(entry)) up into the !prot_numa block.
