128190ebe9 [ARM] Kirkwood: Add MPP44 (board ID) on TS-219
MPP44 can be used to differentiate between one-bay (TS-11x) and
two-bay (TS-21x) devices.

According to an engineer from QNAP, the setting of MPP44 depends
on the firmware rather than hardware.  Presumably, this means
that you could fake the MPP44 value by changing the boot loader.

f8e00530a0 [ARM] orion5x: Set links to solid on D-Link DNS-323
Among other changes, commit b2a731aa ("D-link DNS-323 revision A1 power
LED") changed the default behaviour of the power LED from solid to
blinking.  This was done to match the original DNS-323 firmware which
blinks during the boot process and sets the LED to solid when booting
has completed.  However, the downside of this behaviour is that it
requires userland code to change the LED, even for those who don't
care about the behaviour of the original firmware.  Therefore, change
it to solid again and let those who care about the original behaviour
change the behaviour from userland.

728a756b8f GFS2: rename causes kernel Oops
This patch fixes a kernel Oops in the GFS2 rename code.

The problem was in the way the gfs2 directory code was trying
to re-use sentinel directory entries.

In the failing case, gfs2's rename function was renaming a
file to another name that had the same non-trivial length.
The file being renamed happened to be the first directory
entry on the leaf block.

First, the rename code (gfs2_rename in ops_inode.c) found the
original directory entry and decided it could do its job by
simply replacing the directory entry with another.  Therefore
it determined correctly that no block allocations were needed.

Next, the rename code deleted the old directory entry prior to
replacing it with the new name.  Therefore, the soon-to-be
replaced directory entry was temporarily made into a directory
entry "sentinel" or a place holder at the start of a leaf block.

Lastly, it went to re-add the replacement directory entry in
that leaf block.  However, when gfs2_dirent_find_space was
looking for space in the leaf block, it used the wrong value
for the sentinel.  That threw off its calculations so later
it decides it can't really re-use the sentinel and therefore
must allocate a new leaf block.  But because it previously decided
to re-use the directory entry, it didn't waste the time to
grab a new block allocation for the inode.  Therefore, the
inode's i_alloc pointer was still NULL and it crashes trying to
reference it.

In the case of sentinel directory entries, the entire dirent is
reused, not just the "free space" portion of it, and therefore
the function gfs2_dirent_find_space should use the value 0
rather than GFS2_DIRENT_SIZE(0) for the actual dirent size.

Fixing this calculation enables the reproducer programs to work
properly.

8b4216018b GFS2: BUG in gfs2_adjust_quota
HighMem pages on i686 do not get mapped to the buffer_heads and this was
causing a NULL pointer dereference when we were trying to memset page buffers
to zero.
We now use zero_user() that kmaps the page and directly manipulates page data.
This patch also fixes a boundary condition that was incorrect.

b1becbdee7 GFS2: Fix kernel NULL pointer dereference by dlm_astd
This patch fixes a problem in an error path when looking
up dinodes.  There are two sister-functions, gfs2_inode_lookup
and gfs2_process_unlinked_inode.  Both functions acquire and
hold the i_iopen glock for the dinode being looked up. The last
thing they try to do is hold the i_gl glock for the dinode.
If that glock fails for some reason, the error path was
incorrectly calling gfs2_glock_put for the i_iopen glock twice.
This resulted in the glock being prematurely freed.  The
"minimum hold time" usually kept the glock in memory, but the
lock interface to dlm (aka lock_dlm) freed its memory for the
glock.  In some circumstances, it would cause dlm's dlm_astd daemon
to try to call the bast function for the freed lock_dlm memory,
which resulted in a NULL pointer dereference.

b7dc2df572 GFS2: recovery stuck on transaction lock
This patch fixes bugzilla bug #590878: GFS2: recovery stuck on
transaction lock.  We set the frozen flag on the glock when we receive
a completion that cannot be delivered due to blocked locks. At that
point we check to see whether the first waiting holder has the noexp
flag set. If the noexp lock is queued later, then we need to unfreeze
the glock at that point in time, namely, in the glock work function.

This patch was originally written by Steve Whitehouse, but since
he's on holiday, I'm submitting it.  It's been well tested with a
complex recovery test called revolver.

The python script that did the reduction looks like this:

    os.environ['KCONFIG_NOTIMESTAMP'] = 'Yes, please'

    # XXX: get these using getopt
    kernel_tree = '' # os.path.join(os.environ['HOME'], 'gsrc', 'linux-2.6')
    arch = 'arm'
    target = sys.argv[1]
    defconfig_src = os.path.join(kernel_tree, 'arch/%s/configs/%s' % (arch, target))

    subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])
    origconfig = list(open('.config'))
    config = list(origconfig)
    config_size = os.stat('.config').st_size

    i = 0

    while i < len(config):
        print 'test for %r' % config[i]
        defconfig = open(defconfig_src, 'w')
        defconfig.writelines(config[:i])
        defconfig.writelines(config[i + 1:])
        defconfig.close()
        subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])
        if os.stat('.config').st_size == config_size and list(open('.config')) == origconfig:

            i += 1

    defconfig = open(defconfig_src, 'w')
    defconfig.writelines(config)
    defconfig.close()

which is pretty self-explanatory.

regardless of the physical memory offset.

Recent changes cause problems with how we calculate the start
address, it was always adding the RMO into the start address
which is incorrect. This patch only adds in the RMO offset
if we are in the kexec code path, as it needs the RMO to work
correctly.

Instead of adding the RMO offset in in the common code path, we
can just set r6 to the RMO offset in the kexec code path instead
of to zero, and finally perform the masking in the common code
path

56825c88ff powerpc/cpm: Reintroduce global spi_pram struct (fixes build issue)
spi_t was removed in commit 644b2a680c
("powerpc/cpm: Remove SPI defines and spi structs"), the commit assumed
that spi_t isn't used anywhere outside of the spi_mpc8xxx driver. But
it appears that the struct is needed for micropatch code. So, let's
reintroduce the struct.

Fixes the following build issue:

    CC      arch/powerpc/sysdev/micropatch.o
  micropatch.c: In function 'cpm_load_patch':
  micropatch.c:629: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token

possible reason: unannotated irqs-on.

softirqs last  enabled at (0): [<c005f3e0>] copy_process+0x394/0xe5c
softirqs last disabled at (0): [<(null)>] (null)

Fix this by ensuring that the lockdep interrupt state is manipulated in
the appropriate places.  We essentially treat userspace as an entirely
separate environment which isn't relevant to lockdep (lockdep doesn't
monitor userspace.)  We don't tell lockdep that IRQs will be enabled
in that environment.

Instead, when creating kernel threads (which is a rare event compared
to entering/leaving userspace) we have to update the lockdep state.  Do
this by starting threads with IRQs disabled, and in the kthread helper,
tell lockdep that IRQs are enabled, and enable them.

This provides lockdep with a consistent view of the current IRQ state
in kernel space.

This also revert portions of 0d928b0b61
which didn't fix the problem.

44a54f787c tracing: Add alignment to syscall metadata declarations
For some reason if we declare a static variable and then assign it
later, and the assignment contains a __attribute__((__aligned__(#))),
some versions of gcc will ignore it.

This caused the syscall meta data to not be compact in its section
and caused a kernel oops when the section was being read.

The fix for these versions of gcc seems to be to add the aligned
attribute to the declaration as well.

This fixes the BZ regression:

Fujitsu slightly changed the DMI strings in their recent machines,
(for example the D2778) and this breaks the automatic loading of the

the issue.

436cad2a41 hwmon: (it87) Fix in7 on IT8720F
The IT8720F has no VIN7 pin, so VCCH should always be routed
internally to VIN7 with an internal divider. Curiously, there still
is a configuration bit to control this, which means it can be set
incorrectly. And even more curiously, many boards out there are
improperly configured, even though the IT8720F datasheet claims that
the internal routing of VCCH to VIN7 is the default setting. So we
force the internal routing in this case.

It turns out that all boards with the wrong setting are from Gigabyte,
so I suspect a BIOS bug. But it's easy enough to workaround in the
driver, so let's do it.
