====================
Netfilter/nf_tables fixes for net-next

This patchset contains fixes for recent updates available in your
net-next, they are:

1) Fix double memory allocation for accounting objects that results
   in a leak, this slipped through with the new quota extension,
   patch from Mathieu Poirier.

2) Fix broken ordering when adding set element transactions.

3) Make sure that objects are released in reverse order in the abort
   path, to avoid possible use-after-free when accessing dependencies.

4) Allow to delete several objects (as long as dependencies are
   fulfilled) by using one batch. This includes changes in the use
   counter semantics of the nf_tables objects.

5) Fix illegal sleeping allocation from rcu callback.

net: systemport: fix transmit locking scheme

Our transmit locking scheme did not account for the TX ring full
interrupt. If a TX ring full interrupt fires while we are attempting to
transmit, we will cause a deadlock to occur. Fix this by making sure
that we properly disable interrupts while acquiring the spinlock.

net: phy: fix sparse warning in fixed.c

This commit fixes the following sparse warning:

drivers/net/phy/fixed.c:207
    - warning: symbol 'fixed_phy_del' was not declared.
      Should it be static?

by adding symbol definition to the phy_fixed.h API file. It is ok to do
because the function in question is an exported symbol.

net: filter: fix SKF_AD_PKTTYPE extension on big-endian

BPF classic->internal converter broke SKF_AD_PKTTYPE extension, since

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next

Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

tracing: Convert stddev into u64 in tracepoint benchmark

I've been told that do_div() expects an unsigned 64 bit number, and
is undefined if a signed is used. This gave a warning on the MIPS
build. I'm not sure if a signed 64 bit dividend is really an issue
or not, but the calculation this is used for is standard deviation,
and that isn't going to be negative. We can just convert it to
unsigned and be safe.

ceph: handle cap import atomically

cap import messages are processed by both handle_cap_import() and
handle_cap_grant(). These two functions are not executed in the same
atomic context, so they can races with cap release.

The fix is make handle_cap_import() not release the i_ceph_lock when
it returns. Let handle_cap_grant() release the lock after it finishes
its job.
