Retry the msm_disable_all_modes_commit if it fails with -ERESTARTSYS.
This error would normally propagate up causing the upper layers to
re-trigger the call with the same arguments, but since lastclose
returns a void type the error is getting lost. Therefore detect
-ERESTARTSYS and retry the commit ourselves.

stop_machine: Disable preemption when waking two stopper threads
When cpu_stop_queue_two_works() begins to wake the stopper
threads, it does so without preemption disabled, which leads
to the following race condition:
The source CPU calls cpu_stop_queue_two_works(), with cpu1
as the source CPU, and cpu2 as the destination CPU. When
adding the stopper threads to the wake queue used in this
function, the source CPU stopper thread is added first,
and the destination CPU stopper thread is added last.
When wake_up_q() is invoked to wake the stopper threads, the
threads are woken up in the order that they are queued in,
so the source CPU's stopper thread is woken up first, and
it preempts the thread running on the source CPU.
The stopper thread will then execute on the source CPU,
disable preemption, and begin executing multi_cpu_stop()
and wait for an ack from the destination CPU's stopper thread,
with preemption still disabled. Since the worker thread that
woke up the stopper thread on the source CPU is affine to the
source CPU, and preemption is disabled on the source CPU, that
thread will never run to dequeue the destination CPU's stopper
thread from the wake queue, and thus, the destination CPU's
stopper thread will never run, causing the source CPU's stopper
thread to wait forever, and stall.
Disable preemption when waking the stopper threads in
cpu_stop_queue_two_works() to ensure that the worker thread
that is waking up the stopper threads isn't preempted
by the source CPU's stopper thread, and permanently
scheduled out, leaving the remaining stopper thread asleep
in the wake queue.

There is a comment here which says that DIV_ROUND_UP() and that's where
the problem comes from. Say you pick:
args->bpp = UINT_MAX - 7;
args->width = 4;
args->height = 1;
The integer overflow in DIV_ROUND_UP() means "cpp" is UINT_MAX / 8 and
because of how we picked args->width that means cpp < UINT_MAX / 4.
I've fixed it by preventing the integer overflow in DIV_ROUND_UP(). I
removed the check for !cpp because it's not possible after this change.
I also changed all the 0xffffffffU references to U32_MAX.

[ Upstream commit a4af89286f8fc382459308764ea05935dc477cdc ]
The function dsi_get_cmd_fmt returns enum dsi_cmd_dst_format,
use the correct enum value also for MIPI_DSI_FMT_RGB666/_PACKED.
This has been discovered using clang:
drivers/gpu/drm/msm/dsi/dsi_host.c:743:35: warning: implicit conversion
from enumeration type 'enum dsi_vid_dst_format' to different
enumeration type 'enum dsi_cmd_dst_format' [-Wenum-conversion]
case MIPI_DSI_FMT_RGB666: return VID_DST_FORMAT_RGB666;

[ Upstream commit 3976626ea3d2011f8fd3f3a47070a8b792018253 ]
Commit 62e3a3e342af changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.
However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)
Fixes: 62e3a3e342af ("drm/msm: fix leak in failed get_pages")

Add support for capturing frame on primary through WB using
concurrent writeback HW feature if supported. Changes include
detecting CWB usecase by finding if WB is in clone mode, reserve
same set of hw resources as in plain WB case and program CWB
specific registers like ctrl_top and flush on primary. This change
support dynamic capture enable or disable per frame. Signal only
retire fence for CWB case as primary crtc handles release fence.
WB irq handling is improved using helper functions in virtual encoder.
Change also supports notifying frame error by registering for ping-pong
overflow & signal retire fence with frame error if overflows.

Handle dynamic connector attach or detach of additional
connector on crtc. Avoid full modeset disable and enable
if multiple connectors connected to single CRTC. It allows
seamless handling of usecase like concurrent writeback.
Attempt to keep existing seamless mode checks intact.

If concurrent writeback feature is supported by HW, add a
new property on each CRTC through which client can request
the data point of capture (LM or DSSP output). Availability
of this property on crtc itself is indication for client about
the availability of CWB feature.

Extend crtc implemtation for supporting a copy connector
by limiting roi checks and mixer info population for only
primary connector and remove existing bail out checks to
restrict crtc to single connector.
