Fix up trivial conflicts in fs/btrfs/super.c and fs/fs-writeback.c, and
remove use of INIT_RCU_HEAD in fs/btrfs/extent_io.c (that init macro was
useless and removed in commit 5e8067ad: "rcu head remove init")

The btrfs merge looks like hell, because it changes fs-writeback.c, and
the crazy code has this repeated "estimate number of dirty pages"
counting that involves three different helper functions.  And it's done
in two different places.

Just unify that whole calculation as a "get_nr_dirty_pages()" helper
function, and the merge result will look half-way decent.

The definition of PAGE_CACHE_MASK in <linux/pagemap.h> is needed to use
MAX_RW_COUNT, and on x86-64 that gets done indirectly through the
architecture header includes.  But on MIPS and s390 that doesn't happen,
and we need to make sure that fs/compat.c includes pagemap.h explicitly.

MAX_RW_COUNT truncation that read/write does").

While auditing all tasklist_lock read_lock sites I stumbled over the
following call chain:

audit_prepare_user_tty()
  read_lock(&tasklist_lock);
  tty_audit_push_task();
     mutex_lock(&buf->mutex);

     --> buf->mutex is locked with preemption disabled.

Solve this by acquiring a reference to the task struct under
rcu_read_lock and call tty_audit_push_task outside of the preempt
disabled region.

Move all code which needs to be protected by sighand lock into
tty_audit_push_task() and use lock/unlock_sighand as we do not hold
tasklist_lock.

which was simply to remove the BKL without replacing it — since he'd

| to git commit d585d060(intr_remap: Simplify the code further), which

We need to use irq_remapped() for each irq instead of checking only
intr_remapping_enabled as there might be non remapped irqs even when
remapping is enabled.

Add support for matching by security label (e.g. SELinux context) of
the sender of an user-space audit record.

The audit filter code already allows user space to configure such
filters, but they were ignored during evaluation.  This patch implements
evaluation of these filters.

For example, after application of this patch, PAM authentication logs
caused by cron can be disabled using

Create a snap without waiting for it to commit to disk.  The ioctl is
ordered such that subsequent operations will not be contained by the

wait for the snapshot to commit to disk.
