1f31c3f0e1 Fifth set of fixes for IIO in the 3.16 cycle.
One nasty one that has been around a long time and a couple of non compliant
 ABI fixes.
 
 * The demux code used to split out desired channels for devices that only
   support reading sets of channels at one time had a bug where it was
   building it's conversion tables against the wrong bitmap resulting in
   it never actually demuxing anything.  This is an old bug, but will be
   effecting an increasing number of drivers as it is often used to avoid
   some fiddly code in the individual drivers.
 
 * bma180 and mma8452 weren't obeying the ABI wrt to units for acceleration.
   Were in G rather than m/s^2. A little input check was missing from bma180
   that might lead to acceptance of incorrect values.  This last one is minor
   but might lead to incorrect userspace code working and problems in the
   future.

a0d036b074 drm/i915: Reorder the semaphore deadlock check, again
commit 4be173813e
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Fri Jun 6 10:22:29 2014 +0100

    drm/i915: Reorder semaphore deadlock check

did the majority of the work, but it missed one crucial detail:

The check for the unkickable deadlock on this ring must come after the
check whether the ring that we are waiting on has already passed its
target seqno.

51cbe7e7c4 x86, MCE: Robustify mcheck_init_device
BorisO reports that misc_register() fails often on xen. The current code
unregisters the CPU hotplug notifier in that case. If then a CPU is
offlined and onlined back again, we end up with a second timer running
on that CPU, leading to soft lockups and system hangs.

So let's leave the hotcpu notifier always registered - even if
mce_device_create failed for some cores and never unreg it so that we
can deal with the timer handling accordingly.

58d4e21e50 tracing: Fix wraparound problems in "uptime" trace clock
The "uptime" trace clock added in:

    commit 8aacf017b0
    tracing: Add "uptime" trace clock that uses jiffies

has wraparound problems when the system has been up more
than 1 hour 11 minutes and 34 seconds. It converts jiffies
to nanoseconds using:
        (u64)jiffies_to_usecs(jiffy) * 1000ULL
but since jiffies_to_usecs() only returns a 32-bit value, it
truncates at 2^32 microseconds.  An additional problem on 32-bit
systems is that the argument is "unsigned long", so fixing the
return value only helps until 2^32 jiffies (49.7 days on a HZ=1000
system).

Avoid these problems by using jiffies_64 as our basis, and
not converting to nanoseconds (we do convert to clock_t because
user facing API must not be dependent on internal kernel
HZ values).

35df3b298f batman-adv: fix TT VLAN inconsistency on VLAN re-add
When a VLAN interface (on top of batX) is removed and
re-added within a short timeframe TT does not have enough
time to properly cleanup. This creates an internal TT state
mismatch as the newly created softif_vlan will be
initialized from scratch with a TT client count of zero
(even if TT entries for this VLAN still exist). The
resulting TT messages are bogus due to the counter / tt
client listing mismatch, thus creating inconsistencies on
every node in the network

To fix this issue destroy_vlan() has to not free the VLAN
object immediately but it has to be kept alive until all the
TT entries for this VLAN have been removed. destroy_vlan()
still removes the sysfs folder so that the user has the
feeling that everything went fine.

If the same VLAN is re-added before the old object is free'd,
then the latter is resurrected and re-used.

Implement such behaviour by increasing the reference counter
of a softif_vlan object every time a new local TT entry for
such VLAN is created and remove the object from the list
only when all the TT entries have been destroyed.

tagged VLAN claim frames, claim frames with stacked VLAN headers (QinQ)
should be detected and dropped. Transporting the over the mesh may cause
problems on the receivers, or create bogus entries in the local tt
tables.

====================
xen-netback: Fixing up xenvif_tx_check_gop

This series fixes a lot of bugs on the error path around this function, which
were introduced with my grant mapping series in 3.15. They apply to the latest
net tree, but probably to net-next as well without any modification.
I'll post an another series which applies to 3.15 stable, as the problem was
first discovered there. The only difference is that the "queue" variable name is
replaced to "vif".

1b860da040 xen-netback: Fix releasing header slot on error path
This patch makes this function aware that the first frag and the header might
share the same ring slot. That could happen if the first slot is bigger than
PKT_PROT_LEN. Due to this the error path might release that slot twice or never,
depending on the error scenario.
xenvif_idx_release is also removed from xenvif_idx_unmap, and called separately.

b42cc6e421 xen-netback: Fix releasing frag_list skbs in error path
When the grant operations failed, the skb is freed up eventually, and it tries
to release the frags, if there is any. For the main skb nr_frags is set to 0 to
avoid this, but on the frag_list it iterates through the frags array, and tries
to call put_page on the page pointer which contains garbage at that time.

7801db8aec net_sched: avoid generating same handle for u32 filters
When kernel generates a handle for a u32 filter, it tries to start
from the max in the bucket. So when we have a filter with the max (fff)
handle, it will cause kernel always generates the same handle for new
filters. This can be shown by the following command:

	tc qdisc add dev eth0 ingress
	tc filter add dev eth0 parent ffff: protocol ip pref 770 handle 800::fff u32 match ip protocol 1 0xff
	tc filter add dev eth0 parent ffff: protocol ip pref 770 u32 match ip protocol 1 0xff
	...

we will get some u32 filters with same handle:

 # tc filter show dev eth0 parent ffff:
filter protocol ip pref 770 u32
filter protocol ip pref 770 u32 fh 800: ht divisor 1
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
  match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
  match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
  match 00010000/00ff0000 at 8
filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0
  match 00010000/00ff0000 at 8

handles should be unique. This patch fixes it by looking up a bitmap,
so that can guarantee the handle is as unique as possible. For compatibility,
we still start from 0x800.

Merge tag 'nfs-for-3.16-3' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client fixes from Trond Myklebust:
 "Apologies for the relative lateness of this pull request, however the
  commits fix some issues with the NFS read/write code updates in
  3.16-rc1 that can cause serious Oopsing when using small r/wsize.  The
  delay was mainly due to extra testing to make sure that the fixes
  behave correctly.

  Highlights include;
   - Stable fix for an NFSv3 posix ACL regression
   - Multiple fixes for regressions to the NFS generic read/write code:
     - Fix page splitting bugs that come into play when a small
       rsize/wsize read/write needs to be sent again (due to error
       conditions or page redirty)
     - Fix nfs_wb_page_cancel, which is called by the "invalidatepage"
       method
   - Fix 2 compile warnings about unused variables
   - Fix a performance issue affecting unstable writes"

381676d5e8 iio:bma180: Fix scale factors to report correct acceleration units
The userspace interface for acceleration sensors is documented as using
m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]

The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G
depending on the selected mode.

The scale table was converting to G rather than m/s^2.
Change the scaling table to match the documented interface.

61bd55ce16 iio: buffer: Fix demux table creation
When creating the demux table we need to iterate over the selected scan mask for
the buffer to get the samples which should be copied to destination buffer.
Right now the code uses the mask which contains all active channels, which means
the demux table contains entries which causes it to copy all the samples from
source to destination buffer one by one without doing any demuxing.

commit 99994cd btrfs: dev delete should remove sysfs entry
added a btrfs_kobj_rm_device, which dereferences device->bdev...
right after we check whether device->bdev might be NULL.

I don't honestly know if it's possible to have a NULL device->bdev
here, but assuming that it is (given the test), we need to move
the kobject removal to be under that test.

98ce2deda2 Btrfs: fix abnormal long waiting in fsync
xfstests generic/127 detected this problem.

With commit 7fc34a62ca, now fsync will only flush
data within the passed range.  This is the cause of the above problem,
-- btrfs's fsync has a stage called 'sync log' which will wait for all the
ordered extents it've recorded to finish.

In xfstests/generic/127, with mixed operations such as truncate, fallocate,
punch hole, and mapwrite, we get some pre-allocated extents, and mapwrite will
mmap, and then msync.  And I find that msync will wait for quite a long time
(about 20s in my case), thanks to ftrace, it turns out that the previous
fallocate calls 'btrfs_wait_ordered_range()' to flush dirty pages, but as the
range of dirty pages may be larger than 'btrfs_wait_ordered_range()' wants,
there can be some ordered extents created but not getting corresponding pages
flushed, then they're left in memory until we fsync which runs into the
stage 'sync log', and fsync will just wait for the system writeback thread
to flush those pages and get ordered extents finished, so the latency is
inevitable.

This adds a flush similar to btrfs_start_ordered_extent() in
btrfs_wait_logged_extents() to fix that.

    use the "freeze" sleep state from Zhang Rui.
 
  - Fix for a recently introduced build warning in cpufreq headers from
    Brian W Hart.
 
  - Fix for a 3.13 cpufreq regression related to sysem resume that
    triggers on some systems with multiple CPU clusters from Viresh Kumar.
 
  - Fix for a 3.4 regression in request_firmware() resulting in
    WARN_ON()s on some systems during system resume from Takashi Iwai.
 
  - Revert of the ACPI video commit that changed the default value of
    the video.brightness_switch_enabled command line argument to 0 as
    it has been reported to break existing setups.
 
  - ACPI device enumeration documentation update to take recent code
    changes into account and make the documentation match the code again
    from Darren Hart.

  enumeration documentation update and a few fixes for ARM cpufreq
  drivers.

  Specifics:

   - Fix for a recently introduced NULL pointer dereference in the core
     system suspend code occuring when platforms without ACPI attempt to
     use the "freeze" sleep state from Zhang Rui.

   - Fix for a recently introduced build warning in cpufreq headers from

 "One nouveau deadlock fix, one qxl irq handling fix, and a set of
  radeon pageflipping changes that fix regressions in pageflipping since
  -rc1 along with a leak and backlight fix.

  The pageflipping fixes are a bit bigger than I'd like, but there has
  been a few people focused on testing them"
