There is no need to check for DWARF unwinding support when using the
'dwarf' callchain record method, as this will only ask the kernel to
collect stack dumps for later DWARF CFI processing, which can be done in
another machine, where the support for DWARF unwinding need to be
present.

The in-memory bitmap is not ready when node joins cluster,
so it doesn't make sense to make gather_all_resync_info()
called so earlier, we need to call it after the node's
bitmap is setup. Also, recv_thread could be wake up after
node joins cluster, but it could cause problem if node
receives RESYNCING message without persionality since
mddev->pers->quiesce is called in process_suspend_info.
This commit introduces a new cluster interface load_bitmaps
to fix above problems, load_bitmaps is called in bitmap_load
where bitmap and persionality are ready, and load_bitmaps
does the following tasks:
1. call gather_all_resync_info to load all the node's
bitmap info.
2. set MD_CLUSTER_ALREADY_IN_CLUSTER bit to recv_thread
could be wake up, and wake up recv_thread if there is
pending recv event.
Then ack_bast only wakes up recv_thread after IN_CLUSTER
bit is ready otherwise MD_CLUSTER_PENDING_RESYNC_EVENT is
set.

Some code waits for a metadata update by:
1. flagging that it is needed (MD_CHANGE_DEVS or MD_CHANGE_CLEAN)
2. setting MD_CHANGE_PENDING and waking the management thread
3. waiting for MD_CHANGE_PENDING to be cleared
If the first two are done without locking, the code in md_update_sb()
which checks if it needs to repeat might test if an update is needed
before step 1, then clear MD_CHANGE_PENDING after step 2, resulting
in the wait returning early.
So make sure all places that set MD_CHANGE_PENDING are atomicial, and
bit_clear_unless (suggested by Neil) is introduced for the purpose.

Patch summary:
When showing a cgroupfs entry in mountinfo, show the path of the mount
root dentry relative to the reader's cgroup namespace root.
Short explanation (courtesy of mkerrisk):
If we create a new cgroup namespace, then we want both /proc/self/cgroup
and /proc/self/mountinfo to show cgroup paths that are correctly
virtualized with respect to the cgroup mount point. Previous to this
patch, /proc/self/cgroup shows the right info, but /proc/self/mountinfo
does not.
Long version:
When a uid 0 task which is in freezer cgroup /a/b, unshares a new cgroup
namespace, and then mounts a new instance of the freezer cgroup, the new
mount will be rooted at /a/b. The root dentry field of the mountinfo
entry will show '/a/b'.
cat > /tmp/do1 << EOF
mount -t cgroup -o freezer freezer /mnt
grep freezer /proc/self/mountinfo
EOF
unshare -Gm bash /tmp/do1
> 330 160 0:34 / /sys/fs/cgroup/freezer rw,nosuid,nodev,noexec,relatime - cgroup cgroup rw,freezer
> 355 133 0:34 /a/b /mnt rw,relatime - cgroup freezer rw,freezer
The task's freezer cgroup entry in /proc/self/cgroup will simply show
'/':
grep freezer /proc/self/cgroup
9:freezer:/
If instead the same task simply bind mounts the /a/b cgroup directory,
the resulting mountinfo entry will again show /a/b for the dentry root.
However in this case the task will find its own cgroup at /mnt/a/b,
not at /mnt:
mount --bind /sys/fs/cgroup/freezer/a/b /mnt
130 25 0:34 /a/b /mnt rw,nosuid,nodev,noexec,relatime shared:21 - cgroup cgroup rw,freezer
In other words, there is no way for the task to know, based on what is
in mountinfo, which cgroup directory is its own.
Example (by mkerrisk):
First, a little script to save some typing and verbiage:
echo -e "\t/proc/self/cgroup:\t$(cat /proc/self/cgroup | grep freezer)"
cat /proc/self/mountinfo | grep freezer |
awk '{print "\tmountinfo:\t\t" $4 "\t" $5}'
Create cgroup, place this shell into the cgroup, and look at the state
of the /proc files:
2653
2653 # Our shell
14254 # cat(1)
/proc/self/cgroup: 10:freezer:/a/b
mountinfo: / /sys/fs/cgroup/freezer
Create a shell in new cgroup and mount namespaces. The act of creating
a new cgroup namespace causes the process's current cgroups directories
to become its cgroup root directories. (Here, I'm using my own version
of the "unshare" utility, which takes the same options as the util-linux
version):
Look at the state of the /proc files:
/proc/self/cgroup: 10:freezer:/
mountinfo: / /sys/fs/cgroup/freezer
The third entry in /proc/self/cgroup (the pathname of the cgroup inside
the hierarchy) is correctly virtualized w.r.t. the cgroup namespace, which
is rooted at /a/b in the outer namespace.
However, the info in /proc/self/mountinfo is not for this cgroup
namespace, since we are seeing a duplicate of the mount from the
old mount namespace, and the info there does not correspond to the
new cgroup namespace. However, trying to create a new mount still
doesn't show us the right information in mountinfo:
# propagating to other mountns
/proc/self/cgroup: 7:freezer:/
mountinfo: /a/b /mnt/freezer
The act of creating a new cgroup namespace caused the process's
current freezer directory, "/a/b", to become its cgroup freezer root
directory. In other words, the pathname directory of the directory
within the newly mounted cgroup filesystem should be "/",
but mountinfo wrongly shows us "/a/b". The consequence of this is
that the process in the cgroup namespace cannot correctly construct
the pathname of its cgroup root directory from the information in
/proc/PID/mountinfo.
With this patch, the dentry root field in mountinfo is shown relative
to the reader's cgroup namespace. So the same steps as above:
/proc/self/cgroup: 10:freezer:/a/b
mountinfo: / /sys/fs/cgroup/freezer
/proc/self/cgroup: 10:freezer:/
mountinfo: /../.. /sys/fs/cgroup/freezer
/proc/self/cgroup: 10:freezer:/
mountinfo: / /mnt/freezer

c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option
for loading its xp70 firmware. A previous commit removed this Kconfig
option, as it is apparently harmful, but did not update the driver
code which relied on it.
This patch reworks the firmware loading into the start_feed callback.
At this point we can be sure the rootfs is present, thereby removing
the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

Since the recent rewrite of HD-audio infrastructure,
CONFIG_SND_HDA_RECONFIG has a slightly different meaning. In the
earlier versions, it implicitly assumed only the usage via hwdep sysfs
entries. Meanwhile, in the recent version, this option is meant to
enable the reconfig code in HD-audio driver, which may be used by the
patch loader without hwdep interface.
This patch tries to clarify the usage pattern a bit better, hopefully
avoid the further confusion.

The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn
conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig
warning when it is set:
warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET)
This was apparently hidden by the fact that no ARM platform that
still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we
already have a dependency on GPIOLIB that I added a while ago.
However, after 296ad4acb8ef ("gpio: remove deps on
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable
CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG
as well.
This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET
to guarantee that we can enable the CLKSRC_MMIO driver without
getting warnings.

Merge "non urgent auxdata fix for v4.7 merge window" from Tony Lindgren:
Device tree auxdata handling fix that allows a match based on the
compatible string if no exact match based on the IO address is found.
This leaves out the need to patch auxdata for each driver when adding
new SoCs. And it also reprotedly fixes the issue of passing auxdata
to a child if the parent instantiates the child from DT as discussed
in the "[PATCH] of/platform: Allow secondary compatible match in
of_dev_lookup" mailing list thread.
As a minimal use case, let's also convert omap pinctrl auxdatato
use a generic match.
There is no need to get this in to the v4.6-rc cycle and it can wait
for v4.7 merge window. Note that these changes have now been sitting
in Linux next for about two weeks so far as I wanted to make sure no
new issues are popping up.
