Although private data of sound card instance is usually allocated in the
tail of the instance, drivers in ALSA firewire stack allocate the private
data before allocating the instance. In this case, the private data
should be released explicitly at .private_free callback of the instance.
This commit fixes memory leak following to the above design.

The Analogix DP bridge driver is pretty verbose, and outputs
things like
[ 619.414067] rockchip-dp ff970000.edp: Link Training Clock Recovery success
[ 619.429233] rockchip-dp ff970000.edp: Link Training success!
each time the display gets unblanked. While it is good to know
that the device is behaving correctly, users already know that
because they can see some video output.
Let's keep these messages for cases where we need to actually
debug the driver (we have dynamic debug to enable them at runtime
if need be), and let's keep the kernel quiet otherwise.

We can remove the update-via-batch-buffer code path, which is basically an
effective duplicate of update-via-context-image path, if we notice that
after we have idled the GPU, we can update the context image even of the
kernel context directly. (Update-via-batch-buffer path existed only to
solve the problem of how to update the kernel context image.)
Only additional thing needed is to activate the edited configuration by
sending one empty request down the pipe. This accomplishes context restore
of the updated kernel context and so the OA configuration gets written out
to it's control registers.

Currently, the CCP driver assumes that the SEV command issued to the PSP
will always return (i.e. it will never hang). But recently, firmware bugs
have shown that a command can hang. Since of the SEV commands are used
in probe routines, this can cause boot hangs and/or loss of virtualization
capabilities.
To protect against firmware bugs, add a timeout in the SEV command
execution flow. If a command does not complete within the specified
timeout then return -ETIMEOUT and stop the driver from executing any
further commands since the state of the SEV firmware is unknown.

The supported added for zones in null_blk seem to assume that only rq
based operation is possible. But this depends on the queue_mode setting,
if this is set to 0, then cmd->bio is what we need to be operating on.
Right now any attempt to load null_blk with queue_mode=0 will
insta-crash, since cmd->rq is NULL and null_handle_cmd() assumes it to
always be set.
Make the zoned code deal with bio's instead, or pass in the
appropriate sector/nr_sectors instead.

Currently a uverbs completion event queue is flushed of events in
ib_uverbs_comp_event_close() with the queue spinlock held and then
released. Yet setting ev_queue->is_closed is not set until later in
uverbs_hot_unplug_completion_event_file().
In between the time ib_uverbs_comp_event_close() releases the lock and
uverbs_hot_unplug_completion_event_file() acquires the lock, a completion
event can arrive and be inserted into the event queue by
ib_uverbs_comp_handler().
This can cause a "double add" list_add warning or crash depending on the
kernel configuration, or a memory leak because the event is never dequeued
since the queue is already closed down.
So add setting ev_queue->is_closed = 1 to ib_uverbs_comp_event_close().

DMCU (Display Microcontroller Unit) is a GPU chip involved in

Refresh.
DC is already fully equipped to initialize DMCU as long as the
firmware is loaded.
At the moment only the raven firmware is available.

and split into two ucodes according to the header.
DMCU is optional, so if the firmware is not found, no error or

Commit eeb89e2bb1ac ("x86/efi: Load fixmap GDT in efi_call_phys_epilog()")
moved loading the fixmap in efi_call_phys_epilog() after load_cr3() since
it was assumed to be more logical.
Turns out this is incorrect: In efi_call_phys_prolog(), the gdt with its
physical address is loaded first, and when the %cr3 is reloaded in _epilog
from initial_page_table to swapper_pg_dir again the gdt is no longer
mapped. This results in a triple fault if an interrupt occurs after
load_cr3() and before load_fixmap_gdt(0). Calling load_fixmap_gdt(0) first
restores the execution order prior to commit eeb89e2bb1ac and fixes the
problem.

As a Kernel developer, I make heavy use of "make targz-pkg" in order
to locally compile and remotely install my development Kernels. The
nice feature I rely on is that after a normal "make", "make targz-pkg"
only generates the tarball without having to recompile everything.
That was true until commit f28bc3c32c05 ("tracing: Handle
CC_FLAGS_FTRACE more accurately"). After it, running "make targz-pkg"
after "make" will recompile the whole Kernel tree, making my
development workflow much slower.
The Kernel is choosing to recompile everything because it claims the
command line has changed. A diff of the .cmd files show a repeated
-mfentry in one of the files. That is because "make targz-pkg" calls
"make modules_install" and the environment is already populated with
the exported variables, CC_FLAGS_FTRACE being one of them. Then,
-mfentry gets duplicated because it is not protected behind an ifndef
block, like -pg.
To complicate the problem a little bit more, architectures can define
their own version CC_FLAGS_FTRACE, so our code not only has to
consider recursive Makefiles, but also architecture overrides.
So in this patch we move CC_FLAGS_FTRACE up and unconditionally
define it to -pg. Then we let the architecture Makefiles possibly
override it, and finally append the extra options later. This ensures
the variable is always fully redefined at each invocation so recursive
Makefiles don't keep appending, and hopefully it maintains the
intended behavior on how architectures can override the defaults..
Thanks Steven Rostedt and Vasily Gorbik for the help on this
regression.

Move the chv rotation vs. reflections checks to the plane->check() hook,
away from the (now) platform agnostic
intel_plane_atomic_check_with_state().

Move the display w/a #1175 to a better place. That place
being the new skl+ specific plane->check() hook. This leaves
the skl_check_plane_surface() stuff to deal with the gtt offset
and src coordinate stuff as originally envisioned.

Move the skl+ specific framebuffer related checks from
intel_plane_atomic_check_with_state() into a new function
(skl_plane_check_fb()) which we'll simply call from the skl
plane->check() hook.

Split up intel_check_primary_plane() and intel_check_sprite_plane()
into per-platform variants. This way we can get a unified behaviour
between the SKL universal planes, and we stop checking for non-SKL
specific scaling limits for the "sprite" planes. And we now get
a natural place where to add more plarform specific checks.

We can easily calculate the plane can_scale/min_downscale on demand.
And later on we'll probably want to start calculating these dynamically
based on the cdclk just as skl already does.

To reduce the confusion between a drm plane and the planes of
framebuffers let's desiginate the latter as "color plane".

Stash the gtt_view structure into the plane state. This will become
useful when we do GTT remapping as the gtt_view will not come directly
from the fb anymore.
