Currently the driver passes the PINGPONG index to
dpu_hw_wb_ops::bind_pingpong_blk() callback and uses separate boolean
flag to tell whether WB should be bound or unbound. Simplify this by
passing PINGPONG_NONE in case of unbinding and drop the flag completely.

[Why]
When going from ODM 2:1 single display case to max displays, second
odm pipe needs to be repurposed for one of the new single displays.
However, acquire_first_split_pipe() only handles MPC case and not
ODM case
[How]
Add ODM conditions in acquire_first_split_pipe()
Add commit_minimal_transition_state() in commit_streams() to handle
odm 2:1 exit first, and then process new streams
Handle ODM condition in commit_minimal_transition_state()

commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed
improvements to power consumption over suspend when s0ix wasn't enabled in
BIOS and the system didn't support S3.
This patch however was misguided because the reason the system didn't
support S3 was because SMT was disabled in OEM BIOS setup.
This prevented the BIOS from allowing S3.
Also allowing GPUs to use the s2idle path actually causes problems if
they're invoked on systems that may not support s2idle in the platform
firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails
for any reason, which could lead to unexpected flows.
The original commit also fixed a problem during resume from suspend to idle
without hardware support, but this is no longer necessary with commit
ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven")
Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support")

In commit 95433f726301 ("srcu: Begin offloading srcu_struct fields to
srcu_update"), a new struct srcu_usage field was added, but was not
properly initialized. This led to a "spinlock bad magic" BUG when the
SRCU notifier was ever used. This was observed in the MediaTek CCI
devfreq driver on next-20230525. The trimmed stack trace is as follows:

ggtt offset for hw_tail is not required for the calculations, so drop

On DG2, capturing OA reports while running heavy render workloads
sometimes results in invalid OA reports where 64-byte chunks inside
reports have stale values. Under memory pressure, high OA sampling rates
(13.3 us) and heavy render workload, occasionally, the OA HW TAIL
pointer does not progress as fast as the sampling rate. When these
glitches occur, the TAIL pointer takes approx. 200us to progress. While
this is expected behavior from the HW perspective, invalid reports are
not expected.
In oa_buffer_check_unlocked(), when we execute the if condition, we are
updating the oa_buffer.tail to the aging tail and then setting pollin
based on this tail value, however, we do not have a chance to rewind and
validate the reports prior to setting pollin. The validation happens
in a subsequent call to oa_buffer_check_unlocked(). If a read occurs
before this validation, then we end up reading reports up until this
oa_buffer.tail value which includes invalid reports. Though found on
DG2, this affects all platforms.
The aging tail logic is no longer necessary since we are explicitly
checking for landed reports.
Start by dropping the aging tail logic.
v2:
- Drop extra blank line
- Add reason to drop aging logic (Ashutosh)
- Add bug links (Ashutosh)
- rename aged_tail to read_tail
- Squash patches 3 and 1
v3: (Ashutosh)
- Remove extra spaces
- Remove gtt_offset from the pollin calculation

Update the fallback string for the RTL8821CS from realtek,rtl8822cs-bt
to realtek,rtl8723bs-bt. The difference between these two strings is
that the 8822cs enables power saving features that the 8723bs does not,
and in testing the 8821cs seems to have issues with these power saving
modes enabled.

kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when
creating a file, dir or symlink because the mtime recorded in the
afs_operation struct gets passed to the server by the marshalling routines,
but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it.
This gets masked if a file or directory is subsequently modified.
Fix this by filling in op->mtime before calling the create op.

To comply with the design that buffer objects shall have immutable
cache setting through out their life cycle, {set, get}_caching ioctl's
are no longer supported from MTL onward. With that change caching
policy can only be set at object creation time. The current code
applies a default (platform dependent) cache setting for all objects.
However this is not optimal for performance tuning. The patch extends
the existing gem_create uAPI to let user set PAT index for the object
at creation time.
The new extension is platform independent, so UMD's can switch to using
this extension for older platforms as well, while {set, get}_caching are
still supported on these legacy paltforms for compatibility reason.
However, since PAT index was not clearly defined for platforms prior to
GEN12 (TGL), so we are limiting this externsion to GEN12+ platforms
only. See ext_set_pat() in for the implementation details.
The documentation related to the PAT/MOCS tables is currently available
for Tiger Lake here:
https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/tiger-lake.html
The documentation for other platforms is currently being updated.

We used to only check the alignment of the physical address to decide
which mapping would fit for a certain region of the linear mapping, but
it is not enough since the virtual address must also be aligned, so check
that too.

RISC-V Kfence implementation used to rely on the fact the linear mapping
was backed by at most PMD hugepages, which is not true anymore since
commit 3335068f8721 ("riscv: Use PUD/P4D/PGD pages for the linear
mapping").
Instead of splitting PUD/P4D/PGD mappings afterwards, directly map the
kfence pool region using PTE mappings by allocating this region before
setup_vm_final().

Commit 8aeb7b17f04e ("RISC-V: Make mmap() with PROT_WRITE imply PROT_READ")
allows riscv to use mmap with PROT_WRITE only, and meanwhile mmap with w+x
is also permitted. However, when userspace tries to access this page with
PROT_WRITE|PROT_EXEC, which causes infinite loop at load page fault as
well as it triggers soft lockup. According to riscv privileged spec,
"Writable pages must also be marked readable". The fix to drop the
`PAGE_COPY_READ_EXEC` and then `PAGE_COPY_EXEC` would be just used instead.
This aligns the other arches (i.e arm64) for protection_map.

Anastasios reported crash on stable 5.15 kernel with following

SEC("lsm.s/bprm_creds_for_exec")
int BPF_PROG(bprm_creds_for_exec, struct linux_binprm *bprm)

char p[128] = { 0 };
bpf_d_path(path, p, 128);
return 0;
}
But bprm->executable can be NULL, so bpf_d_path call will crash:

It's problem for all stable trees with bpf_d_path helper, which was
added in 5.9.
This issue is fixed in current bpf code, where we identify and mark
trusted pointers, so the above code would fail even to load.
For the sake of the stable trees and to workaround potentially broken
verifier in the future, adding the code that reads the path object from
the passed pointer and verifies it's valid in kernel space.

The user-space policy of the gpio-sim is that configuration for lines
with offsets outside the bounds of the corresponding bank is ignored,
but gpio-sim is still using that configuration when constructing the
sim. In the case of named lines this results in temporarily allocating
space for names that are not used, and for hogs results in errors being
logged when the gpio-sim attempts to register the out of range hog with
gpiolib:
gpiochip_machine_hog: unable to get GPIO desc: -22
Add checks to filter out any line configuration outside the bounds
of the bank when constructing the sim.
