Replace disable_kq parameter with user_queue parameter.
The parameter has the following logic:
-1 = auto (ASIC specific default)
0 = user queues disabled
1 = user queues enabled and kernel queues enabled (if supported)
2 = user queues enabled and kernel queues disabled
The default behavior (-1) is currently the same as 0 for current
ASICs. To enable user queues (in addition to kernel queues) set
user_queue=1. To enable user queues and disable kernel queues
(to make all resources available to user queues), set user_queue=2.

1) Checkpatch complains if we print an error message for kzalloc()
failure. The kzalloc() failure already has it's own error messages
built in. Also this allocation is small enough that it is guaranteed
to succeed.
2) Return directly instead of doing a goto free_fence_drv. The

The goto frees "fence_drv" so this is a double free bug. There is no
need to call amdgpu_seq64_free(adev, fence_drv->va) since the seq64

This patch introduces new function pointers in the amdgpu_sdma structure
to handle queue stop, start and soft reset operations. These will replace
the older callback mechanism.
The new functions are:
- stop_kernel_queue: Stops a specific SDMA queue
- start_kernel_queue: Starts/Restores a specific SDMA queue
- soft_reset_kernel_queue: Performs soft reset on a specific SDMA queue
v2: Update stop_queue/start_queue function paramters to use ring pointer instead of device/instance(Chritian)
v3: move stop_queue/start_queue to struct amdgpu_sdma_instance and rename them. (Alex)
v4: rework the ordering a bit (Alex)

%p4cc is designed for DRM/V4L2 FourCCs with their specific quirks, but
it's useful to be able to print generic 4-character codes formatted as
an integer. Extend it to add format specifiers for printing generic
32-bit FourCCs with various endian semantics:
%p4ch Host byte order
%p4cn Network byte order
%p4cl Little-endian
%p4cb Big-endian
The endianness determines how bytes are interpreted as a u32, and the
FourCC is then always printed MSByte-first (this is the opposite of
V4L/DRM FourCCs). This covers most practical cases, e.g. %p4cn would
allow printing LSByte-first FourCCs stored in host endian order
(other than the hex form being in character order, not the integer
value).

Syzbot managed to come up with a filesystem where check/repair got
rather confused at finding a reflink pointer in the inodes btree.
Currently, the "key allowed in this btree" checks only apply at commit
time, not read time - for forwards compatibility. It seems this is too
loose.
Now, strict key type allowed checks apply:
- at commit time (no forward compatibility issues)
- for btree node pointers
- if it's a known btree, known key type, and the key type has the
"BKEY_TYPE_strict_btree_checks" flag.
This means we still have the option of using generic key types - e.g.
KEY_TYPE_error, KEY_TYPE_set - on more existing btrees in the future,
while most key types that are intended for only a specific btree get
stricter checks.

I had left the warning around but as a non-fatal error to get my gcc-15
builds going, but fixed up some of the most annoying warning cases so
that it wouldn't be *too* verbose.
Because I like the _concept_ of the warning, even if I detested the
implementation to shut it up.
It turns out the implementation to shut it up is even more broken than I
thought, and my "shut up most of the warnings" patch just caused fatal
errors on gcc-14 instead.
I had tested with clang, but when I upgrade my development environment,
I try to do it on all machines because I hate having different systems
to maintain, and hadn't realized that gcc-14 now had issues.
The ACPI case is literally why I wanted to have a *type* that doesn't
trigger the warning (see commit d5d45a7f2619: "gcc-15: make
'unterminated string initialization' just a warning"), instead of
marking individual places as "__nonstring".
But gcc-14 doesn't like that __nonstring location that shut gcc-15 up,
because it's on an array of char arrays, not on one single array:
drivers/acpi/tables.c:399:1: error: 'nonstring' attribute ignored on objects of type 'const char[][4]' [-Werror=attributes]
399 | static const char table_sigs[][ACPI_NAMESEG_SIZE] __initconst __nonstring = {
| ^~~~~~
and my attempts to nest it properly with a type had failed, because of
how gcc doesn't like marking the types as having attributes, only
symbols.
There may be some trick to it, but I was already annoyed by the bad
attribute design, now I'm just entirely fed up with it.
I wish gcc had a proper way to say "this type is a *byte* array, not a
string".
The obvious thing would be to distinguish between "char []" and an
explicitly signed "unsigned char []" (as opposed to an implicitly
unsigned char, which is typically an architecture-specific default, but
for the kernel is universal thanks to '-funsigned-char').
But any "we can typedef a 8-bit type to not become a string just because
it's an array" model would be fine.
But "__attribute__((nonstring))" is sadly not that sane model.

RK3588 integrates the Analogix eDP 1.3 TX controller IP and the HDMI/eDP
TX Combo PHY based on a Samsung IP block. There are also two independent
eDP display interface with different address on RK3588 Soc.
The patch currently adds only the basic support, specifically RGB output
up to 4K@60Hz, without the tests for audio, PSR and other eDP 1.3 specific
features.
In additon, the above Analogix IP has always been utilized as eDP on
Rockchip platform, despite its capability to also support the DP v1.2.
Therefore, the newly added logs will contain the term 'edp' rather than
'dp'. And the newly added 'apb' reset control is to ensure the APB bus
of eDP controller works well on the RK3588 SoC.
