b819ed4b2a pNFS/flexfiles: Improve merging of errors in LAYOUTRETURN
When we hit 22 errors, we start to overflow the memory buffers allocated
to the LAYOUTRETURN errors. The issue is that currently, RPC call reply
ordering determines how successful we are in merging errors that refer
to contiguous READ or WRITE requests.

Fix is to use an insertion sort to help detect contiguity.

187d131dd9 libceph: invalidate AUTH in addition to a service ticket
If we fault due to authentication, we invalidate the service ticket we
have and request a new one - the idea being that if a service rejected
our authorizer, it must have expired, despite mon_client's attempts at
periodic renewal.  (The other possibility is that our ticket is too new
and the service hasn't gotten it yet, in which case invalidating isn't
necessary but doesn't hurt.)

Invalidating just the service ticket is not enough, though.  If we
assume a failure on mon_client's part to renew a service ticket, we
have to assume the same for the AUTH ticket.  If our AUTH ticket is
bad, we won't get any service tickets no matter how hard we try, so
invalidate AUTH ticket along with the service ticket.

Back in 2013, commit 4b8e8b5d78 ("libceph: fix authorizer

doesn't force us to request any new secrets in any way and therefore we
never get out of the exponential backoff mode:

f6330cc1f0 libceph: clear messenger auth_retry flag if we fault
Commit 20e55c4cc7 ("libceph: clear messenger auth_retry flag when we

67645d7619 libceph: fix ceph_msg_revoke()
There are a number of problems with revoking a "was sending" message:

(1) We never make any attempt to revoke data - only kvecs contibute to
con->out_skip.  However, once the header (envelope) is written to the
socket, our peer learns data_len and sets itself to expect at least
data_len bytes to follow front or front+middle.  If ceph_msg_revoke()
is called while the messenger is sending message's data portion,
anything we send after that call is counted by the OSD towards the now
revoked message's data portion.  The effects vary, the most common one
is the eventual hang - higher layers get stuck waiting for the reply to
the message that was sent out after ceph_msg_revoke() returned and
treated by the OSD as a bunch of data bytes.  This is what Matt ran
into.

(2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs
is wrong.  If ceph_msg_revoke() is called before the tag is sent out or
while the messenger is sending the header, we will get a connection
reset, either due to a bad tag (0 is not a valid tag) or a bad header
CRC, which kind of defeats the purpose of revoke.  Currently the kernel
client refuses to work with header CRCs disabled, but that will likely
change in the future, making this even worse.

(3) con->out_skip is not reset on connection reset, leading to one or
more spurious connection resets if we happen to get a real one between
con->out_skip is set in ceph_msg_revoke() and before it's cleared in
write_partial_skip().

Fixing (1) and (3) is trivial.  The idea behind fixing (2) is to never
zero the tag or the header, i.e. send out tag+header regardless of when
ceph_msg_revoke() is called.  That way the header is always correct, no
unnecessary resets are induced and revoke stands ready for disabled
CRCs.  Since ceph_msg_revoke() rips out con->out_msg, introduce a new
"message out temp" and copy the header into it before sending.

c8fe9b17d0 ceph: Asynchronous IO support
The basic idea of AIO support is simple, just call kiocb::ki_complete()
in OSD request's complete callback. But there are several special cases.

when IO span multiple objects, we need to wait until all OSD requests
are complete, then call kiocb::ki_complete(). Error handling in this case
is tricky too. For simplify, AIO both span multiple objects and extends
i_size are not allowed.

Another special case is check EOF for reading (other client can write to
the file and extend i_size concurrently). For simplify, the direct-IO/AIO
code path does do the check, fallback to normal syn read instead.

2deeb47729 IB/sa: Fix netlink local service GFP crash
The rdma netlink local service registers a handler to handle RESOLVE
response and another handler to handle SET_TIMEOUT request. The first
thing these handlers do is to call netlink_capable() to check the
access right of the received skb to make sure that the sender has root
access. Under normal conditions, such responses and requests will be
directly forwarded to the handlers without going through the netlink_dump
pathway (see ibnl_rcv_msg() in drivers/infiniband/core/netlink.c).
However, a user application could send a RESOLVE request (not response)
to the local service, which will fall into the netlink_dump pathway,
where a new skb will be created without initializing the control block.
This new skb will be eventually forwarded to the local service RESOLVE
response handler. Unfortunately, netlink_capable() will cause general
protection fault if the skb's control block is not initialized. This
patch will address the problem by checking the skb first.

230323dac0 ALSA: timer: Handle disconnection more safely
Currently ALSA timer device doesn't take the disconnection into
account very well; it merely unlinks the timer device at disconnection
callback but does nothing else.  Because of this, when an application
accessing the timer device is disconnected, it may release the
resource before actually closed.  In most cases, it results in a
warning message indicating a leftover timer instance like:
   ALSA: timer xxxx is busy?
But basically this is an open race.

This patch tries to address it.  The strategy is like other ALSA
devices: namely,
- Manage card's refcount at each open/close
- Wake up the pending tasks at disconnection
- Check the shutdown flag appropriately at each possible call

Note that this patch has one ugly hack to handle the wakeup of pending
tasks.  It'd be cleaner to introduce a new disconnect op to
snd_timer_instance ops.  But since it would lead to internal ABI
breakage and it eventually increase my own work when backporting to
stable kernels, I took a different path to implement locally in
timer.c.  A cleanup patch will follow at next for 4.5 kernel.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over
  system suspend/resume cycles if they have been runtime-suspended
  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

  Specifics:

   - Modify the driver core and the USB subsystem to allow USB devices
     to stay suspended over system suspend/resume cycles if they have
     been runtime-suspended already beforehand and fix some bugs on top
     of these changes (Tomeu Vizoso, Rafael Wysocki).

   - Update ACPICA to upstream revision 20160108, including updates of
     the ACPICA's copyright notices, a code fixup resulting from a
     regression fix that was necessary in the upstream code only (the
     regression fixed by it has never been present in Linux) and a
     compiler warning fix (Bob Moore, Lv Zheng).

   - Fix a recent regression in the cpuidle menu governor that broke it
     on practically all architectures other than x86 and make a couple
     of optimizations on top of that fix (Rafael Wysocki).

   - Clean up the selection of cpuidle governors depending on whether or
     not the kernel is configured for tickless systems (Jean Delvare).

   - Revert a recent commit that introduced a regression in the ACPI
     backlight driver, address the problem it attempted to fix in a
     different way and revert one more cosmetic change depending on the
     problematic commit (Hans de Goede).

   - Add two more ACPI backlight quirks (Hans de Goede).

   - Fix a few minor problems in the core devfreq code, clean it up a
     bit and update the MAINTAINERS information related to it (Chanwoo
     Choi, MyungJoo Ham).

   - Improve an error message in the ACPI fan driver (Andy Lutomirski).

   - Fix a recent build regression in the cpupower tool (Shreyas
     Prabhu)"

3549d82279 SH Drivers Updates for v4.5
Clean up the clock API on legacy SH to make it more similar to the Common
 Clock Framework.  This will avoid different behaviour in drivers shared
 between legacy and CCF-based platforms (e.g. SCIF).

9638685e32 ARM: SoC driver updates for v4.5
Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
 but also some other driver updates that don't belong anywhere else. We also
 bring in the drivers/reset code through arm-soc.
 
 Some of the larger updates:
 
 - Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
   parts of the chip/board on these platforms, all proprietary protocols that
   don't fit into other subsystems and live in drivers/soc for now.
 
 - System bus driver for UniPhier
 - Driver for the TI Wakeup M3 IPC device
 
 - Power management for Raspberry PI
 
 + Again a bunch of other smaller updates and patches.

f9cd69fe5e ARM: SoC defconfig updates for v4.5
As usual, a bunch of commits, mostly adding drivers and other options to
 defconfigs because it makes sense to have them enabled on various development
 or product boards. Too much to enumerate each here.
 
 There's an introduction of a pxa_defconfig, since PXA finally will allow
 building a shared kernel for all boards. With this, we can hopefully
 remove a bunch of individual defconfigs down the road but it requires
 a bit of real life testing and transition period.
