Junxiao Bi 88dbe98dc7 ocfs2: o2hb: don't negotiate if last hb fail
Sometimes io error is returned when storage is down for a while.  Like
for iscsi device, stroage is made offline when session timeout, and this
will make all io return -EIO.  For this case, nodes shouldn't do
negotiate timeout but should fence self.  So let nodes fence self when
o2hb_do_disk_heartbeat return an error, this is the same behavior with
o2hb without negotiate timer.

Junxiao Bi e76f8237a2 ocfs2: o2hb: add NEGOTIATE_APPROVE message
This message is used to re-queue write timeout timer and negotiate timer
when all nodes suffer a write hung to storage, this makes node not fence

This message is sent to master node when non-master nodes's negotiate

Junxiao Bi e0cbb79805 ocfs2: o2hb: add negotiate timer
This series of patches is to fix the issue that when storage down, all
nodes will fence self due to write timeout.

With this patch set, all nodes will keep going until storage back
online, except if the following issue happens, then all nodes will do as
before to fence self.

1. io error got
2. network between nodes down
3. nodes panic

This patch (of 6):

When storage down, all nodes will fence self due to write timeout.  The
negotiate timer is designed to avoid this, with it node will wait until
storage up again.

Negotiate timer working in the following way:

1. The timer expires before write timeout timer, its timeout is half
   of write timeout now.  It is re-queued along with write timeout timer.
   If expires, it will send NEGO_TIMEOUT message to master node(node with
   lowest node number).  This message does nothing but marks a bit in a
   bitmap recording which nodes are negotiating timeout on master node.

2. If storage down, nodes will send this message to master node, then
   when master node finds its bitmap including all online nodes, it sends
   NEGO_APPROVL message to all nodes one by one, this message will
   re-queue write timeout timer and negotiate timer.  For any node doesn't
   receive this message or meets some issue when handling this message, it
   will be fenced.  If storage up at any time, o2hb_thread will run and
   re-queue all the timer, nothing will be affected by these two steps.

Rajneesh Bhardwaj b740d2e923 platform/x86: Add PMC Driver for Intel Core SoC
This patch adds the Power Management Controller driver as a PCI driver
for Intel Core SoC architecture.

This driver can utilize debugging capabilities and supported features
as exposed by the Power Management Controller.

Please refer to the below specification for more details on PMC features.
http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html

The current version of this driver exposes SLP_S0_RESIDENCY counter.
This counter can be used for detecting fragile SLP_S0 signal related
failures and take corrective actions when PCH SLP_S0 signal is not
asserted after kernel freeze as part of suspend to idle flow
(echo freeze > /sys/power/state).

Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it
detects favorable conditions to enter its low power mode. As a
pre-requisite the SoC should be in deepest possible Package C-State
and devices should be in low power mode. For example, on Skylake SoC
the deepest Package C-State is Package C10 or PC10. Suspend to idle
flow generally leads to PC10 state but PC10 state may not be sufficient
for realizing the platform wide power potential which SLP_S0 signal
assertion can provide.

SLP_S0 signal is often connected to the Embedded Controller (EC) and the
Power Management IC (PMIC) for other platform power management related
optimizations.

In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes
power gated + PLL Idle.

As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed
as an API and also debugfs features are added to indicate SLP_S0 signal
assertion residency in microseconds.

echo freeze > /sys/power/state
wake the system
cat /sys/kernel/debug/pmc_core/slp_s0_residency_usec

Gabriele Mazzotta ff8651237f dell-rbtn: Ignore ACPI notifications if device is suspended
Some BIOSes unconditionally send an ACPI notification to RBTN when the
system is resuming from suspend. This makes dell-rbtn send an input
event to userspace as if a function key was pressed. Prevent this by
ignoring all the notifications received while the device is suspended.

Microsoft Surface Book has a tablet mode button. Print another message

Unfortunately, proper support involves the _DSM method, which is not a

Takashi Iwai eb4606e64a ASoC: Updates for v4.7 part 2
Really sorry about this late pull request.  It looks like at the time I
 sent my pull request for v4.7 there was some conflict or other issue
 which caused my script to stop merging the ASoC branches at some point
 after the HDMI changes.
 
 It's all specific driver updates, including:
 
  - New drivers for MAX98371 and TAS5720.
  - SPI support for TLV320AIC32x4.
  - TDM support for STI Uniperf IPs.
 
 This code should all have been in -next prior to the merge window apart
 from some fixes, it dropped out on the 18th.

I stumbled multiple times over 'return_i2c_dev', especially before the
actual 'return res'. It makes the code hard to read, so reanme the
function to 'put_i2c_dev' which also better matches 'get_free_i2c_dev'.

Vivek Goyal 21765194ce ovl: Do d_type check only if work dir creation was successful
d_type check requires successful creation of workdir as iterates
through work dir and expects work dir to be present in it. If that's
not the case, this check will always return d_type not supported even
if underlying filesystem might be supporting it.

So don't do this check if work dir creation failed in previous step.

Antonio Murdaca 3fe6e52f06 ovl: override creds with the ones from the superblock mounter
In user namespace the whiteout creation fails with -EPERM because the
current process isn't capable(CAP_SYS_ADMIN) when setting xattr.

A simple reproducer:

$ mkdir upper lower work merged lower/dir
$ sudo mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work merged
$ unshare -m -p -f -U -r bash

Now as root in the user namespace:

\# touch merged/dir/{1,2,3} # this will force a copy up of lower/dir
\# rm -fR merged/*

This ends up failing with -EPERM after the files in dir has been
correctly deleted:

unlinkat(4, "2", 0)                     = 0
unlinkat(4, "1", 0)                     = 0
unlinkat(4, "3", 0)                     = 0
close(4)                                = 0
unlinkat(AT_FDCWD, "merged/dir", AT_REMOVEDIR) = -1 EPERM (Operation not
permitted)

Interestingly, if you don't place files in merged/dir you can remove it,
meaning if upper/dir does not exist, creating the char device file works
properly in that same location.

This patch uses ovl_sb_creator_cred() to get the cred struct from the
superblock mounter and override the old cred with these new ones so that
the whiteout creation is possible because overlay is wrong in assuming that
the creds it will get with prepare_creds will be in the initial user
namespace.  The old cap_raise game is removed in favor of just overriding
the old cred struct.

This patch also drops from ovl_copy_up_one() the following two lines:

override_cred->fsuid = stat->uid;
override_cred->fsgid = stat->gid;

This is because the correct uid and gid are taken directly with the stat
struct and correctly set with ovl_set_attr().
