That will allow to cleanup the rest of the code right after,

84e345e4e2 time, Fix setting of hardware clock in NTP code
At init time, if the system time is "warped" forward in warp_clock()
it will differ from the hardware clock by sys_tz.tz_minuteswest.  This time
difference is not taken into account when ntp updates the hardware clock,
and this causes the system time to jump forward by this offset every reboot.

The kernel must take this offset into account when writing the system time
to the hardware clock in the ntp code.  This patch adds
persistent_clock_is_local which indicates that an offset has been applied
in warp_clock() and accounts for the "warp" before writing the hardware
clock.

x86 does not have this problem as rtc writes are software limited to a
+/-15 minute window relative to the current rtc time.  Other arches, such
as powerpc, however do a full synchronization of the system time to the
rtc and will see this problem.

d6d3c4e656 OF: convert devtree lock from rw_lock to raw spinlock
With the locking cleanup in place (from "OF: Fixup resursive
locking code paths"), we can now do the conversion from the
rw_lock to a raw spinlock as required for preempt-rt.

The previous cleanup and this conversion were originally
separate since they predated when mainline got raw spinlock (in
commit c2f21ce2e3 "locking: Implement new raw_spinlock").

So, at that point in time, the cleanup was considered plausible
for mainline, but not this conversion.  In any case, we've kept
them separate as it makes for easier review and better bisection.

03536e23ac net: sctp: sctp_auth_make_key_vector: use sctp_auth_create_key
In sctp_auth_make_key_vector, we allocate a temporary sctp_auth_bytes
structure with kmalloc instead of the sctp_auth_create_key allocator.
Change this to sctp_auth_create_key as it is the case everywhere else,
so that we also can properly free it via sctp_auth_key_put. This makes
it easier for future code changes in the structure and allocator itself,
since a single API is consistently used for this purpose. Also, by
using sctp_auth_create_key we're doing sanity checks over the arguments.

3807ff5899 macvlan: add a salt to mc_hash()
Some multicast addresses are common to all macvlans,
so if a multicast message has a hash value collision, we
have to deliver a copy to all macvlans, adding significant
latency and possible packet drops if netdev_max_backlog
limit is hit.

Having a per macvlan hash function permits to reduce the
impact of hash collisions.

01a7decf75 nfsd: keep a checksum of the first 256 bytes of request
Now that we're allowing more DRC entries, it becomes a lot easier to hit
problems with XID collisions. In order to mitigate those, calculate a
checksum of up to the first 256 bytes of each request coming in and store
that in the cache entry, along with the total length of the request.

This initially used crc32, but Chuck Lever and Jim Rees pointed out that
crc32 is probably more heavyweight than we really need for generating
these checksums, and recommended looking at using the same routines that
are used to generate checksums for IP packets.

On an x86_64 KVM guest measurements with ftrace showed ~800ns to use
csum_partial vs ~1750ns for crc32.  The difference probably isn't
terribly significant, but for now we may as well use csum_partial.

3992313488 Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King:
 "I was going to hold these off until v3.8 was out, and send them with a
  stable tag, but as everyone else is pushing much bigger fixes which
  Linus is accepting, let's save people from the hastle of having to
  patch v3.8 back into working or use a stable kernel.

  Looking at the diffstat, this really is high value for its size; this
  is miniscule compared to how the -rc6 to tip diffstat currently looks.

  So, four patches in this set:
   - Punit Agrawal reports that the kernel no longer boots on MPCore due
     to a new assumption made in the GIC code which isn't true of
     earlier GIC designs.  This is the biggest change in this set.
   - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
     the DT-ification of the GIC support without fixing up non-DT
     Realview - which now sees a greater number of interrupts than it
     did before.
   - A fix for the DMA coherent code from Marek which uses the wrong
     check for atomic allocations; this can result in spinlock lockups
     or other nasty effects.
   - A fix from Will, which will affect all Android based platforms if
     not applied (which use the 2G:2G VM split) - this causes
     particularly 'make' to misbehave unless this bug is fixed."

4c190e2f91 sunrpc: trim off trailing checksum before returning decrypted or integrity authenticated buffer
When GSSAPI integrity signatures are in use, or when we're using GSSAPI
privacy with the v2 token format, there is a trailing checksum on the
xdr_buf that is returned.

It's checked during the authentication stage, and afterward nothing
cares about it. Ordinarily, it's not a problem since the XDR code
generally ignores it, but it will be when we try to compute a checksum
over the buffer to help prevent XID collisions in the duplicate reply
cache.

Fix the code to trim off the checksums after verifying them. Note that
in unwrap_integ_data, we must avoid trying to reverify the checksum if
the request was deferred since it will no longer be present when it's
revisited.

====================
Please accept this pull request intended for the 3.9 stream!

Included are a mac80211 pull, an iwlwifi pull (actually two -- one
was a fast-forward), a wl12xx pull, and a couple of Bluetooth pulls.

On mac80211, Johannes says:

"I've included
 * AKM definitions from Bing,
 * mesh fixes from Thomas, including a fix from him for me breaking his
   patch while applying,
 * channel check fix from Simon,
 * an old patch from Yoni Divinsky who doesn't even work for TI any
   more, to configure the WEP TX key for ARP offload etc.
 * MAC ACL API from Vasanth
 * a fix for the infamous chanctx_conf warning from Arnd
 * from myself, a fix for my previous aggregation changes, some cleanup
   and some improvements and fixes for WoWLAN"

On iwlwifi, Johannes says:

"Two small changes for iwlwifi-next, one to update all our Copyright
notices and one to provide the RX page order."

And also:

"So what I have here is some cleanups, preparations and the new MVM
(multi-virtual MAC) driver itself and (this is new) some work on the
transport API as well as a message flooding fix."

On wl12xx, Luca says:

"Lots of bugfixes and improvements in our TI wireless drivers,
including support for multi-channel.  Intended for 3.9."

On Bluetooth, Gustavo says:

"This is my first pull request to 3.9. The biggest changes here are from Johan
Hedberg who made a lot of fixes in the Management interface. The issues arose
due to a new test tool we wrote and the usage of the Management interface as
default in BlueZ 5. The rest of the patches are more clean ups and small
fixes."

And also:

"Here goes another batch intended for 3.9, the majority of the patch here are
from Johan who is fixing many issues in the management interface that have
appeared lately. The rest of the patches are just small improvements, fixes
and clean ups."

Along with those are the usual variety of updates/enhancements to
the mwl8k, mwifiex, ath9k, rtlwifi, and rt2x00 drivers as well as
a few updates for the ssb and bcma busses.  I don't think there are
any big headliners there.

Please let me know if there are problems!

Trinity (the syscall fuzzer) discovered that reading /proc/dgrp/info was
leaking some memory. Fix by using the correct release op in info_proc_file_ops.

Commit 8a424bf40d (tools/usb: remove last USBFS
user) removed 'usbfs' files from the source but retained mentions of 'usbfs'
all over the place, most importantly in the misleading error messages printed
in case USB device files are not there.  Remove all the  mentions of 'usbfs'
for good now!

should be zeroed out before the memory is returned, as we already do

6ba542a291 net: sctp: sctp_setsockopt_auth_key: use kzfree instead of kfree
In sctp_setsockopt_auth_key, we create a temporary copy of the user
passed shared auth key for the endpoint or association and after
internal setup, we free it right away. Since it's sensitive data, we
should zero out the key before returning the memory back to the
allocator. Thus, use kzfree instead of kfree, just as we do in
sctp_auth_key_put().

Currently netdev gets created possibly after returning from

del_station and while it waits the 400ms remote side will already
