The parenthesis are in the wrong place so the original code is
equivalent to:
if (!xen_feature(XENFEAT_writable_descriptor_tables)) { ...
Which obviously was not intended.

Since (69b34fb netfilter: xt_LOG: add net namespace support
for xt_LOG), we hit this:
[ 4224.708977] BUG: unable to handle kernel NULL pointer dereference at 0000000000000388

when callling log functions from conntrack both in and out
are NULL i.e. the net pointer is invalid.
Adding struct net *net in call to nf_logfn() will secure that
there always is a vaild net ptr.

Tony Jones reported that the ftrace self tests on s390 do not work:
<6>Testing dynamic ftrace ops #1: (0 0 0 0 0) FAILED!
<6>Testing tracer irqsoff:
<3>failed to start irqsoff tracer
<4>.. no entries found ..FAILED!
<6>Testing tracer wakeup:
<3>failed to start wakeup tracer
<4>.. no entries found ..FAILED!
<6>Testing tracer function_graph:
<4>Failed to init function_graph tracer, init returned -19
<4>FAILED!
This happens because we forgot to adjust the instruction pointer that gets
passed to the ftrace trace function by MCOUNT_INSN_SIZE.
In addition change MCOUNT_INSN_SIZE to the correct value on 31 bit.
It only worked so far because the to be patched instruction was identical.

On heavy paging load some guest cpus started to loop in gmap_ipte_notify.
This was visible as stalled cpus inside the guest. The gmap_ipte_notifier
tries to map a user page and then made sure that the pte is valid and
writable. Turns out that with the software change bit tracking the pte
can become read-only (and only software writable) if the page is clean.
Since we loop in this code, the page would stay clean and, therefore,
be never writable again.
Let us just use fixup_user_fault, that guarantees to call handle_mm_fault.

It is possible for one thread to to take se_sess->sess_cmd_lock in
core_tmr_abort_task() before taking a reference count on
se_cmd->cmd_kref, while another thread in target_put_sess_cmd() drops
se_cmd->cmd_kref before taking se_sess->sess_cmd_lock.
This introduces kref_put_spinlock_irqsave() and uses it in
target_put_sess_cmd() to close the race window.

This patch fixes a regression bug introduced in v3.9-rc1 where if the
underlying struct block_device for a IBLOCK backend is configured with
WCE=1 + DPOFUA=1 settings, the rw = WRITE assignment no longer occurs
in iblock_execute_rw(), and rw = 0 is passed to iblock_submit_bios()
in effect causing a READ bio operation to occur.
The offending commit is:

Stacking drivers may append bvecs to existing bio's, resulting
in non-zero bi_idx conditions. This patch counts the loops of
bio_for_each_segment() rather than inheriting the bi_idx value
to pass as a segment count to the hardware submission routine.

The Kconfig entry for BCACHE selects CLOSURES. But there's no Kconfig

but was removed when the closures code was no longer provided as a
