Currently, we can ask to authenticate DATA chunks and we can send DATA
chunks on the same packet as COOKIE_ECHO, but if you try to combine
both, the DATA chunk will be sent unauthenticated and peer won't accept
it, leading to a communication failure.
This happens because even though the data was queued after it was
requested to authenticate DATA chunks, it was also queued before we
could know that remote peer can handle authenticating, so
sctp_auth_send_cid() returns false.
The fix is whenever we set up an active key, re-check send queue for
chunks that now should be authenticated. As a result, such packet will
now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.

Rework the crtc event/flip_wait system as follows:
- If we enable a crtc (full modeset), we set omap_crtc->pending and
register vblank irq.
- If we need to set GO bit (page flip), we do the same but also set the
GO bit.
- On vblank we unregister the irq, clear the 'pending' flag, send vblank
event to userspace if crtc->state->event != NULL, and wake up
'pending_wait' wq.
- In omap_atomic_complete() we wait for the 'pending' flag to get reset
for all enabled crtcs using 'pending_wait' wq.
The above ensures that we send the events to userspace in vblank, and
that after the wait in omap_atomic_complete() everything for the
affected crtcs has been completed.

Neil Horman pointed out a problem where if he did something like this
receive A
snap A B
change B
send -p A B
and then on another box do
recieve A
receive B
the receive B would fail because we use the UUID of A for the clone sources for
B. This makes sense most of the time because normally you are sending from the
original sources, not a received source. However when you use a recieved subvol
its UUID is going to be something completely different, so if you then try to
receive the diff on a different volume it won't find the UUID because the new A
will be something else. The only constant is the received uuid. So instead
check to see if we have received_uuid set on the root, and if so use that as the
clone source, as btrfs receive looks for matches either in received_uuid or
uuid. Thanks,

Commit 32e55a777f83 ("ARM: 8389/1: Add cpu_resume_arm() for firmwares
that resume in ARM state") needed to introduce a new usage of BSYM()
to fix a problem with a previous patch. This in turn causes a conflict
with the "bsym" branch which removes this symbol, replacing it with a
'badr' assembly macro. Fix this up.

In Thumb2 mode, the stack register r13 is deprecated if the
destination register is the program counter (r15). Similar to
head.S, head-nommu.S uses r13 to store the return address used
after configuring the CPU's CP15 register. However, since we do
not enable a MMU, there will be no address switch and it is
possible to use branch with link instruction to call
__after_proc_init.
Avoid using r13 completely by using bl to call __after_proc_init
and get rid of __secondary_switched.
Beside removing unnecessary complexity, this also fixes a
compiler warning when compiling a !MMU kernel:
Warning: Use of r13 as a source register is deprecated when r15
is the destination register.

Some platforms always enter the kernel in the ARM state even if
the kernel is compiled for THUMB2. Add a small wrapper on top of
cpu_resume() that switches into THUMB2 state.
This provides the functionality to fix a problem reported by Kevin
Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2
kernel because the platform's firmware always enters the kernel in
ARM mode from deep idle states.
(rmk: tweaked to work without BSYM->badr changes.)

Before atomic modesetting omap_framebuffer_pin() and
omap_framebuffer_unpin() were always called with modesetting locks
taken. With atomic modesetting support this is no longer the case, and
we need locking to protect the pin_count and the paddr, as multiple
threads may pin the same fb concurrently.
This patch adds a mutex to struct omap_framebuffer, and uses it in
omap_framebuffer_pin() and omap_framebuffer_unpin().

DRM page flip vblank events requested by page flips or atomic commits
are created by the DRM core and then passed to driver through CRTC
states (for atomic commit) or directly to the page flip handler (for
legacy page flips). The events are then kept aside until the page flip
completes, at which point drivers queue them for delivery with a call to
drm_send_vblank_event().
When a DRM file handle is closed events pending for delivery are cleaned
up automatically by the DRM core. Events that have been passed to the
driver but haven't completed yet, however, are not handled by the DRM
core. Drivers are responsible for destroying them and must not attempt
to queue them for delivery. This is usually handled by drivers'
preclose() handlers that cancel and destroy page flip events that
reference the file handle being closed.
With asynchronous atomic updates the story becomes more complex. Several
asynchronous atomic updates can be pending, each of them carrying
per-CRTC events. As the atomic_commit() operation doesn't receive a file
handle context, drivers can't know which file handle a pending update
refers to, making it difficult to cancel or wait for completion of
updates related to the file handle being closed.
It should be noted that cancelling page flips or waiting for atomic
updates completion isn't required by the DRM core when closing a file
handle. The only requirement is that no event gets queued for delivery
after the preclose() operation returns. This can easily be achieved by
storing events for atomic commits in a list, unlinking events from the
file handle being closed by setting the file_priv field to NULL, and
skipping delivery of unlinked events.
This logic replaces the page flip cancellation completely.

The field tracks the plane state to avoid double-enable or -disable.
This isn't required anymore, as
- the DRM atomic core guarantees that the plane atomic_update and
atomic_disable functions will never be called on an enabled/disabled
plane
- the CRTC enable/disable operations that enable/disable the plane are
already guarded against double enable/disable
We can thus remove the enabled field completely. The
omap_plane_set_enable() function then becomes a wrapper around
omap_plane_setup() which can be called directly.
