Modify Power_supply greybus driver to support runtime PM framework.
During charging state, the driver will block remote device of suspending,
and then enables runtime suspend when remote device is in none chargin
state.
Testing Done: Compiled and verified on EVT2, EVT2 1x2 GPB test module
and Device class daughter board.

Now jack-button are registered to snd framework based on capabilities
populated by codec module's topology data. Thus, valid ids for button
events can also vary for different modules. This patch modifies existing
button reporting mechanism to avoid reporting spurious button events for
invalid button ids.

Now jack & jack-buttons are registered to snd_jack framework based on
the capability shared by module's topology data. Thus, jack events
should be reported to above snd framework only in case corresponding
jack type is registered. This patch adds additional checks to avoid

Added extra fields namely jack_mask & button_mask for each module_info.
These fields are required while registering jack & reporting jack
events.
Earlier, these were hard coded values assuming fixed capabilities say
HEADSET, LINEOUT, etc. supported by GB-codec driver. Now these are
computed dynamically based on module's jack capability shared via
topology data.

This patch adds extra field jack_type to gb_audio_topology struct. Also,
it defines bit fields to be used by module while defining it's jack and
jack-button capabilities.
Currently, module can populate a single jack and associated buttons. In
case multiple jacks are supported data routing (say duplicating, etc.)
should be handled within module's FW. It can populate additional mixer
controls to do so.

tick_nohz_start_idle() is prevented to be called if the idle tick can't
be stopped since commit 1f3b0f8243cb934 ("tick/nohz: Optimize nohz idle

kvm guest will softlockup:

The idle and iowait states are weird 0 for cpu0(housekeeping).
The bug is present in both guest and host kernels, and they both have
cpu0's idle and iowait states issue, however, host kernel's suspend/resume
path etc will touch watchdog to avoid the softlockup.
- The watchdog will not be touched in tick_nohz_stop_idle path (need be
touched since the scheduler stall is expected) if idle_active flags are
not detected.
- The idle and iowait states will not be accounted when exit idle loop
(resched or interrupt) if idle start time and idle_active flags are
not set.
This patch fixes it by reverting commit 1f3b0f8243cb934 since can't stop
idle tick doesn't mean can't be idle.

Commit fec1d0115240 ("[PATCH] Disable CLONE_CHILD_CLEARTID for abnormal
exit") has caused a subtle regression in nscd which uses
CLONE_CHILD_CLEARTID to clear the nscd_certainly_running flag in the
shared databases, so that the clients are notified when nscd is
restarted. Now, when nscd uses a non-persistent database, clients that
have it mapped keep thinking the database is being updated by nscd, when
in fact nscd has created a new (anonymous) one (for non-persistent
databases it uses an unlinked file as backend).
The original proposal for the CLONE_CHILD_CLEARTID change claimed
(https://lkml.org/lkml/2006/10/25/233):
: The NPTL library uses the CLONE_CHILD_CLEARTID flag on clone() syscalls
: on behalf of pthread_create() library calls. This feature is used to
: request that the kernel clear the thread-id in user space (at an address
: provided in the syscall) when the thread disassociates itself from the
: address space, which is done in mm_release().
:
: Unfortunately, when a multi-threaded process incurs a core dump (such as
: from a SIGSEGV), the core-dumping thread sends SIGKILL signals to all of
: the other threads, which then proceed to clear their user-space tids
: before synchronizing in exit_mm() with the start of core dumping. This
: misrepresents the state of process's address space at the time of the
: SIGSEGV and makes it more difficult for someone to debug NPTL and glibc
: problems (misleading him/her to conclude that the threads had gone away
: before the fault).
:
: The fix below is to simply avoid the CLONE_CHILD_CLEARTID action if a
: core dump has been initiated.
The resulting patch from Roland (https://lkml.org/lkml/2006/10/26/269)
seems to have a larger scope than the original patch asked for. It
seems that limitting the scope of the check to core dumping should work
for SIGSEGV issue describe above.

__printk_nmi_flush() can be called from nmi_panic(), therefore it has to
test whether it's executed in NMI context and thus must route the
messages through deferred printk() or via direct printk().
This is to avoid potential deadlocks, as described in commit
cf9b1106c81c ("printk/nmi: flush NMI messages on the system panic").
However there remain two places where __printk_nmi_flush() does
unconditional direct printk() calls:
- pr_err("printk_nmi_flush: internal error ...")
- pr_cont("\n")
Factor out print_nmi_seq_line() parts into a new printk_nmi_flush_line()
function, which takes care of in_nmi(), and use it in
__printk_nmi_flush() for printing and error-reporting.

buddy allocator
Firmware Assisted Dump (FA_DUMP) on ppc64 reserves substantial amounts
of memory when booting a secondary kernel. Srikar Dronamraju reported
that multiple nodes may have no memory managed by the buddy allocator
but still return true for populated_zone().
Commit 1d82de618ddd ("mm, vmscan: make kswapd reclaim in terms of
nodes") was reported to cause kswapd to spin at 100% CPU usage when
fadump was enabled. The old code happened to deal with the situation of
a populated node with zero free pages by co-incidence but the current
code tries to reclaim populated zones without realising that is
impossible.
We cannot just convert populated_zone() as many existing users really
need to check for present_pages. This patch introduces a managed_zone()
helper and uses it in the few cases where it is critical that the check
is made for managed pages -- zonelist construction and page reclaim.

.config:867:warning: override: CC_OPTIMIZE_FOR_SIZE changes choice state
I've made a previous attempt at fixing them and we discussed a number of
alternatives.
I tried changing the Makefile to use "merge_config.sh -n
$(fragment-list)" but couldn't get that to work properly.
This is yet another approach, based on the observation that we do want
to see a warning for conflicting 'choice' options, and that we can
simply make them non-conflicting by listing all other options as
disabled. This is a trivial patch that we can apply independent of
plans for other changes.

If kexec_apply_relocations fails, kexec_load_purgatory frees pi->sechdrs
and pi->purgatory_buf. This is redundant, because in case of error
kimage_file_prepare_segments calls kimage_file_post_load_cleanup, which
will also free those buffers.
This causes two warnings like the following, one for pi->sechdrs and the
other for pi->purgatory_buf:

There have been several reports about pre-mature OOM killer invocation
in 4.7 kernel when order-2 allocation request (for the kernel stack)
invoked OOM killer even during basic workloads (light IO or even kernel
compile on some filesystems). In all reported cases the memory is
fragmented and there are no order-2+ pages available. There is usually
a large amount of slab memory (usually dentries/inodes) and further
debugging has shown that there are way too many unmovable blocks which
are skipped during the compaction. Multiple reporters have confirmed
that the current linux-next which includes [1] and [2] helped and OOMs
are not reproducible anymore.
A simpler fix for the late rc and stable is to simply ignore the
compaction feedback and retry as long as there is a reclaim progress and
we are not getting OOM for order-0 pages. We already do that for
CONFING_COMPACTION=n so let's reuse the same code when compaction is
enabled as well.

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs and iomap fixes from Dave Chinner:
"Most of these changes are small regression fixes that address problems
introduced in the 4.8-rc1 window. The two fixes that aren't (IO
completion fix and superblock inprogress check) are fixes for problems
introduced some time ago and need to be pushed back to stable kernels.
Changes in this update:
- iomap FIEMAP_EXTENT_MERGED usage fix
- additional mount-time feature restrictions
- rmap btree query fixes
- freeze/unmount io completion workqueue fix
- memory corruption fix for deferred operations handling"
* tag 'xfs-iomap-for-linus-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs:
xfs: track log done items directly in the deferred pending work item
iomap: don't set FIEMAP_EXTENT_MERGED for extent based filesystems
xfs: prevent dropping ioend completions during buftarg wait
xfs: fix superblock inprogress check
xfs: simple btree query range should look right if LE lookup fails
xfs: fix some key handling problems in _btree_simple_query_range
xfs: don't log the entire end of the AGF
xfs: disallow mounting of realtime + rmap filesystems
xfs: don't perform lookups on zero-height btrees
