From Paul Walmsley <paul@pwsan.com> via Tony Lindgren:
Move some of the OMAP2+ CM and System Control Module direct
register accesses into CM- and System Control
Module-specific "drivers" underneath arch/arm/mach-omap2/. This
is a prerequisite for moving this code out of arch/arm/mach-omap2/ into
drivers/.
Basic test logs are available here:

With this machine deleted, there is no need to maintain the

The arg64 struct has a hole after ->buf_size which isn't cleared. Or if
any of the calls to copy_from_user() fail then that would cause an
information leak as well.
This was assigned CVE-2013-2147.

Pull ceph fixes from Sage Weil:
"These fix several bugs with RBD from 3.11 that didn't get tested in
time for the merge window: some error handling, a use-after-free, and
a sequencing issue when unmapping and image races with a notify
operation.
There is also a patch fixing a problem with the new ceph + fscache
code that just went in"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
fscache: check consistency does not decrement refcount
rbd: fix error handling from rbd_snap_name()
rbd: ignore unmapped snapshots that no longer exist
rbd: fix use-after free of rbd_dev->disk
rbd: make rbd_obj_notify_ack() synchronous
rbd: complete notifies before cleaning up osd_client and rbd_dev
libceph: add function to ensure notifies are complete
After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

Add pd->name to output for these debugging messages.
Remove normally compiled out pkt_dbg(2, ...) function entry tracing
equivalents as it's better done via the function tracer.

Use the more common pkt_dbg(level, fmt, ...) form.
These messages are emitted at KERN_NOTICE.
Always emit function name with pkt_dbg(2, ...) uses and remove the
sometimes abbreviated embedded function name.
This form always verifies the format and arguments.

If the system has trouble allocating memory for the creation of the aoe
debugfs directory or of a file inside it, the debugfs member of an aoedev
can be NULL.
Do not treat a NULL debugfs pointer as a BUG on aoedev shutdown, avoiding
the user impact of an unecessary panic.

This series adds the debugging information that the coraid.com-distributed
aoe driver exports via sysfs, but instead of sysfs, it uses debugfs.
With these patches applied, even without AoE targets on the network, KEDR
reports new possible memory leaks, but these are from callers outside the
aoe driver that have used aoe_devnode to get the name of the character
devices through the aoe_class->devnode callback, and I believe they're
responsible for freeing that memory.
This patch:
Create and destroy the debugfs directory.
