ab83a38958 axnet_cs: use spin_lock_irqsave in ax_interrupt
Use spin_lock_irqsave instead of spin_lock in ax_interrupt because
the interrupt handler can also be invoked from ei_watchdog.

336a283b9c dsa: Fix Kconfig dependencies.
Based upon a report by Randy Dunlap.

DSA needs PHYLIB, but PHYLIB needs NET_ETHERNET.  So, in order
to select PHYLIB we have to make DSA depend upon NET_ETHERNET.

This is a big change, but results in no loss of information, despite us

and Grant Likely thinks powerpc can also use the same reduction
technique.

The python script that did the reduction looks like this:

    # This prevents including a timestamp in the .config which makes comparing a
    # bit easier.
    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:
            del config[i]
        else:
            i += 1

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

which is pretty self-explanatory.

e372357ba5 ocfs2: tighten up strlen() checking
This function is only called from one place and it's like this:
	dlm_register_domain(conn->cc_name, dlm_key, &fs_version);

The "conn->cc_name" is 64 characters long.  If strlen(conn->cc_name)
were equal to O2NM_MAX_NAME_LEN (64) that would be a bug because
strlen() doesn't count the NULL character.

In fact, if you look how O2NM_MAX_NAME_LEN is used, it mostly describes
64 character buffers.  The only exception is nd_name from struct
o2nm_node.

Anyway I looked into it and in this case the domain string comes from
osb->uuid_str in ocfs2_setup_osb_uuid().  That's 32 characters and NULL
which easily fits into O2NM_MAX_NAME_LEN.  This patch doesn't change how
the code works, but I think it makes the code a little cleaner.

a78f9f4668 ocfs2: make xattr extension work with new local alloc reservation.
The old ocfs2_xattr_extent_allocation is too optimistic about
the clusters we can get. So actually if the file system is
too fragmented, ocfs2_add_clusters_in_btree will return us
with EGAIN and we need to allocate clusters once again.

So this patch change it to a while loop so that we can allocate
clusters until we reach clusters_to_add.

693c241a5f ocfs2: No need to zero pages past i_size.
When ocfs2 fills a hole, it does so by allocating clusters.  When a
cluster is larger than the write, ocfs2 must zero the portions of the
cluster outside of the write.  If the clustersize is smaller than a
pagecache page, this is handled by the normal pagecache mechanisms, but
when the clustersize is larger than a page, ocfs2's write code will zero
the pages adjacent to the write.  This makes sure the entire cluster is
zeroed correctly.

Currently ocfs2 behaves exactly the same when writing past i_size.
However, this means ocfs2 is writing zeroed pages for portions of a new
cluster that are beyond i_size.  The page writeback code isn't expecting
this.  It treats all pages past the one containing i_size as left behind
due to a previous truncate operation.

Thankfully, ocfs2 calculates the number of pages it will be working on
up front.  The rest of the write code merely honors the original
calculation.  We can simply trim the number of pages to only cover the
actual file data.

77154a2026 powerpc/fsl-booke: Fix address issue when using relocatable kernels
When booting a relocatable kernel it needs to jump to the correct
start address, which for BookE parts is usually unchanged
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

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:

faabd47f7e hwmon: Fix autoloading of fschmd on recent Fujitsu machines
Fujitsu slightly changed the DMI strings in their recent machines,
(for example the D2778) and this breaks the automatic loading of the
needed fschmd driver. Being more tolerant on string comparison fixes
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.

398aa66827 ARM: 6212/1: atomic ops: add memory constraints to inline asm
Currently, the 32-bit and 64-bit atomic operations on ARM do not
include memory constraints in the inline assembly blocks. In the
case of barrier-less operations [for example, atomic_add], this
means that the compiler may constant fold values which have actually
been modified by a call to an atomic operation.

This issue can be observed in the atomic64_test routine in
<kernel root>/lib/atomic64_test.c:

00000000 <test_atomic64>:

  50:	ebfffffe 	bl	0 <__bug>
  54:	00000000 	.word	0x00000000

The atomic64_set (0x38-0x44) writes to the atomic64_t, but the
compiler doesn't see this, assumes the test condition is always
false and generates an unconditional branch to __bug. The rest of the
test is optimised away.

This patch adds suitable memory constraints to the atomic operations on ARM
to ensure that the compiler is informed of the correct data hazards. We have
to use the "Qo" constraints to avoid hitting the GCC anomaly described at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44492 , where the compiler
makes assumptions about the writeback in the addressing mode used by the
inline assembly. These constraints forbid the use of auto{inc,dec} addressing
modes, so it doesn't matter if we don't use the operand exactly once.

068de8d1be ARM: 6211/1: atomic ops: fix register constraints for atomic64_add_unless
The atomic64_add_unless function compares an atomic variable with
a given value and, if they are not equal, adds another given value
to the atomic variable. The function returns zero if the addition
did not occur and non-zero otherwise.

On ARM, the return value is initialised to 1 in C code. Inline assembly
code then performs the atomic64_add_unless operation, setting the
return value to 0 iff the addition does not occur. This means that
when the addition *does* occur, the value of ret must be preserved
across the inline assembly and therefore requires a "+r" constraint
rather than the current one of "=&r".

Thanks to Nicolas Pitre for helping to spot this.

ac0547dc62 ALSA: hda - Restore cleared pin controls on resume
Many codecs now clear the pin controls at suspend via snd_hda_shutup_pins()
for reducing the click noise at power-off.  But this leaves some pins
uninitialized, and they'll be never recovered after resume.

This patch adds the proper recovery of cleared pin controls on resume.
Also it adds a check of bus->shutdown so that pins won't be cleared at
module unloading.
