In function parameters, `u32 data[]` decays to `u32 *`, making
the array syntax misleading and triggering
-Wsizeof-array-argument warnings.
Replace the array-style parameter with an explicit pointer type
to match the actual semantics and silence the warning.

This change adds the below gpu memory tracepoint:
gpu_mem/gpu_mem_total: track global or proc gpu memory total usages
Per process tracking of total gpu memory usage in the gem layer is not
appropriate and hard to implement with trivial overhead. So for the gfx
device driver layer to track total gpu memory usage both globally and
per process in an easy and uniform way is to integrate the tracepoint in
this patch to the underlying varied implementations of gpu memory
tracking system from vendors.
Putting this tracepoint in the common trace events can not only help
wean the gfx drivers off of debugfs but also greatly help the downstream
Android gpu vendors because debugfs is to be deprecated in the upcoming
Android release. Then the gpu memory tracking of both Android kernel and
the upstream linux kernel can stay closely, which can benefit the whole
kernel eco-system in the long term.

commit 4b848f20eda5974020f043ca14bacf7a7e634fc8 upstream.
There's two references floating around here (for the object reference,
not the handle_count reference, that's a different thing):
- The temporary reference held by vgem_gem_create, acquired by
creating the object and released by calling
drm_gem_object_put_unlocked.
- The reference held by the object handle, created by
drm_gem_handle_create. This one generally outlives the function,
except if a 2nd thread races with a GEM_CLOSE ioctl call.
So usually everything is correct, except in that race case, where the
access to gem_object->size could be looking at freed data already.
Which again isn't a real problem (userspace shot its feet off already
with the race, we could return garbage), but maybe someone can exploit
this as an information leak.

Currently, separate submissions are made for page table
switch and context switch to the ring buffer. However, if the
page table switch succeeds but the context switch fails,
it can lead to use of wrong page table for drawctxt.
To address this issue, rollback the pagetable to current pagetable.
Also,correctly put the refcount of adreno context during error
cleanup.

2. GMU power perf counters are unused and we are out of register address

3. Remove PWR counter group safely for a6xx targets and setup the

4. IFPC counters are moved to part of target specific code and enabled

commit 4cf949c7fafe21e085a4ee386bb2dade9067316e upstream.
Invalid userspace dma surface copies could potentially overflow
the memcpy from the surface to the snooped image leading to crashes.
To fix it the dimensions of the copybox have to be validated
against the expected size of the snooped cursor.

commit 6fdc2d490ea1369d17afd7e6eb66fecc5b7209bc upstream.
A typical DP-MST unplug removes a KMS connector. However care must
be taken to properly synchronize with user-space. The expected
sequence of events is the following:
1. The kernel notices that the DP-MST port is gone.
2. The kernel marks the connector as disconnected, then sends a
uevent to make user-space re-scan the connector list.
3. User-space notices the connector goes from connected to disconnected,
disables it.
4. Kernel handles the IOCTL disabling the connector. On success,
the very last reference to the struct drm_connector is dropped and
drm_connector_cleanup() is called.
5. The connector is removed from the list, and a uevent is sent to tell
user-space that the connector disappeared.
The very last step was missing. As a result, user-space thought the
connector still existed and could try to disable it again. Since the
kernel no longer knows about the connector, that would end up with
EINVAL and confused user-space.
Fix this by sending a hotplug uevent from drm_connector_cleanup().

[ Upstream commit 0ad811cc08a937d875cbad0149c1bab17f84ba05 ]
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:

[ Upstream commit 442cf8e22ba25a77cb9092d78733fdbac9844e50 ]
struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.
Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.
Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.
