This patch fixes a particular type of data corruption that has been
encountered when loading a snapshot's metadata from disk.
When we allocate a new chunk in persistent_prepare, we increment
ps->next_free and we make sure that it doesn't point to a metadata area
by further incrementing it if necessary.
When we load metadata from disk on device activation, ps->next_free is
positioned after the last used data chunk. However, if this last used
data chunk is followed by a metadata area, ps->next_free is positioned
erroneously to the metadata area. A newly-allocated chunk is placed at
the same location as the metadata area, resulting in data or metadata
corruption.
This patch changes the code so that ps->next_free skips the metadata
area when metadata are loaded in function read_exceptions.
The patch also moves a piece of code from persistent_prepare_exception
to a separate function skip_metadata to avoid code duplication.

The profile introspection seq file has a locking bug when policy is viewed
from a virtual root (task in a policy namespace), introspection from the
real root is not affected.
The test for root
while (parent) {
is correct for the real root, but incorrect for tasks in a policy namespace.
This allows the task to walk backup the policy tree past its virtual root
causing it to be unlocked before the virtual root should be in the p_stop
fn.
This results in the following lockdep back trace:

One bug fix and three reverts. The reverts back out the slightly
controversial feeding the entire device tree into the random pool and
the reserved-memory binding which isn't fully baked yet. Expect the
reserved-memory patches at least to resurface for v3.13. The bug fixes
removes a scary but harmless warning on SPARC that was introduced in the
v3.12 merge window. v3.13 will contain a proper fix that makes the new
code work on SPARC.
On the plus side, the diffstat looks *awesome*. I love removing lines of code.

We use jump label to enable pv-spinlock. With the changes in (442e0973e9
Merge branch 'x86/jumplabel'), the jump label behaviour has changed
that would result in eventual hang of the VM since we would end up in a
situation where slow path locks would halt the vcpus but we will not be
able to wakeup the vcpu by lock releaser using unlock kick.
Similar problem in Xen and more detailed description is available in
a945928ea2 (xen: Do not enable spinlocks before jump_label_init()
has executed)
This patch splits kvm_spinlock_init to separate jump label changes with
pvops patching and also make jump label enabling after jump_label_init().

The pcm_usb_stream plugin requires the mremap explicitly for the read
buffer, as it expands itself once after reading the required size.
But the commit [314e51b9: mm: kill vma flag VM_RESERVED and
mm->reserved_vm counter] converted blindly to a combination of
VM_DONTEXPAND | VM_DONTDUMP like other normal drivers, and this
resulted in the failure of mremap().
For fixing this regression, we need to remove VM_DONTEXPAND for the
read-buffer mmap.

Functions that walk the ntstatus_to_dos_map[] array could
run off the end. For example, ntstatus_to_dos() loops
while ntstatus_to_dos_map[].ntstatus is not 0. Granted,
this is mostly theoretical, but could be used as a DOS attack
if the error code in the SMB header is bogus.

This reverts commit 109b623629.
Tim Bird expressed concern that this will have a bad effect on boot
time, and while simple tests have shown it to be okay with simple tree,
a device tree blob can potentially be quite large and
add_device_randomness() is not a fast function. Rather than do this for
all platforms unconditionally, I'm reverting this patch and would like
to see it revisited. Instead of feeding the entire tree into the random
pool, it would probably be appropriate to hash the tree and feed the
hash result into the pool. There really isn't a lot of randomness in a
device tree anyway. In the majority of cases only a handful of
properties are going to be different between machines with the same
baseboard.

Not all DT platforms have all the cpus collected under a /cpus node.
That just happens to be a details of FDT, ePAPR and PowerPC platforms.
Sparc does something different, but unfortunately the current code
complains with a warning if /cpus isn't there. This became a problem
with commit f86e4718, "driver/core cpu: initialize of_node in cpu's
device structure", which caused the function to get called for all
architectures.
This commit is a temporary fix to fail silently if the cpus node isn't
present. A proper fix will come later to allow arch code to provide a
custom mechanism for decoding the CPU hwid if the 'reg' property isn't
appropriate.

The create_bind_cap_vol_ctl does not create any control indicating
that an inverted dmic is present. Therefore, create multiple
capture volumes in this scenario, so we always have some indication
that the internal mic is inverted.
This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13
(both are based on the CX20590 codec), but the fix is generic and
could be needed for other codecs/machines too.
Thanks to Szymon Acedański for the pointer and a draft patch.

I have a randconfig here which has enabled only
CONFIG_MICROCODE=y
CONFIG_MICROCODE_OLD_INTERFACE=y
with both
# CONFIG_MICROCODE_INTEL is not set
# CONFIG_MICROCODE_AMD is not set
off. Which makes building the microcode functionality a little
pointless. Don't do that in such cases then.

Pull watchdog fixes from Wim Van Sebroeck:
"This will fix a deadlock on the ts72xx_wdt driver, fix bitmasks in the
kempld_wdt driver and fix a section mismatch in the sunxi_wdt driver"
* git://www.linux-watchdog.org/linux-watchdog:
watchdog: sunxi: Fix section mismatch
watchdog: kempld_wdt: Fix bit mask definition
watchdog: ts72xx_wdt: locking bug in ioctl
This driver has a section mismatch, for probe and remove functions,
leading to the following warning during the compilation.
WARNING: drivers/watchdog/built-in.o(.data+0x24): Section mismatch in
reference from the variable sunxi_wdt_driver to the function
.init.text:sunxi_wdt_probe()

STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)'
handles [9:8] bits. Thus, it should be fixed in order to handle
[5:4] bits.
