evergreen_default_state and evergreen_default_size are only
used in evergreen.c. Single file symbols should be static.
So move their definitions to evergreen_blit_shaders.h
and change their storage-class-specifier to static.
Remove unneeded evergreen_blit_shader.c
evergreen_ps/vs definitions were removed with
commit 4f8629675800 ("drm/radeon/kms: remove r6xx+ blit copy routines")
So their declarations in evergreen_blit_shader.h
are not needed, so remove them.

Smatch reports this issue
virtual_link_hwss.c:32:6: warning: symbol
'virtual_setup_stream_attribute' was not declared.
Should it be static?
virtual_setup_stream_attribute is only used in
virtual_link_hwss.c, but the other functions in the
file are declared in the header file and used elsewhere.
For consistency, add the virtual_setup_stream_attribute
decl to virtual_link_hwss.h.

In function si_parse_power_table(), array adev->pm.dpm.ps and its member
is allocated. If the allocation of each member fails, the array itself
is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function
returns an error.
This leads to potential double free of the array adev->pm.dpm.ps, as
well as leak of its array members, since the members are not freed in
the allocation function and the array is not nulled when freed.
In addition adev->pm.dpm.num_ps, which keeps track of the allocated
array member, is not updated until the member allocation is
successfully finished, this could also lead to either use after free,
or uninitialized variable access in si_dpm_fini().
Fix this by postponing the free of the array until si_dpm_fini() and
increment adev->pm.dpm.num_ps everytime the array member is allocated.

Clarify the smu_cmn_send_smc_msg_with_param documentation to mention two
cases exist where messages are silently dropped with no error returned.
These cases occur in unusual situations where either:
1. the message type is not allowed to a virtual GPU, or
2. a PCI recovery is underway and the HW is not yet in sync with the SW
For more details see
commit 4ea5081c82c4 ("drm/amd/powerplay: enable SMC message filter")
commit bf36b52e781d ("drm/amdgpu: Avoid accessing HW when suspending SW state")

prone. If there was a typo error, a new node will be created instead of
extending the existing node. This will lead to run-time errors that

(during build time). This also reduces the indentation making the code

This reverts commit e2a88eabb02410267519b838fb9b79f5206769be. The commit
in question makes msm_use_mmu() check whether the DRM 'component master'
device is translated by the IOMMU. At this moment it is the 'mdss'
device.
However on platforms using the MDP5 driver (e.g. MSM8916/APQ8016,
MSM8996/APQ8096) it's the mdp5 device, which has the iommus property
(and thus is "translated by the IOMMU"). This results in these devices
being broken with the following lines in the dmesg.
[drm] Initialized msm 1.9.0 20130625 for 1a00000.mdss on minor 0

msm 1a00000.mdss: [drm:msm_fbdev_create] *ERROR* failed to allocate fb
Getting the mdp5 device pointer from this function is not that easy at
this moment. Thus this patch is reverted till the MDSS rework [1] lands.
It will make the mdp5/dpu1 device component master and the check will be
legit.

Commit abfc426d1b2f ("block: pass a block_device to bio_clone_fast")
calls the modified bio_alloc_clone() in bcache code as:
bio_init_clone(bio->bi_bdev, bio, orig_bio, GFP_NOIO);
But the first parameter is wrong, where bio->bi_bdev should be
orig_bio->bi_bdev. The wrong bi_bdev panics the kernel when submitting
cache bio.
This patch fixes the wrong bdev parameter usage and avoid the panic.

Commit a7c50c940477 ("block: pass a block_device and opf to bio_reset")
moves bch_bio_map() inside journal_write_unlocked() next to the location
where the modified bio_reset() was called.
This change is wrong because calling bch_bio_map() immediately after
bio_reset(), a BUG_ON(!bio->bi_iter.bi_size) inside bch_bio_map() will
be triggered and panic the kernel.
This patch puts bch_bio_map() back to its original correct location in
journal_write_unlocked() and avoid the BUG_ON().

The llvm patch [1] enabled opaque pointer which caused selftest
'exhandler' failure.
...
; work = task->task_works;
7: (79) r1 = *(u64 *)(r6 +2120) ; R1_w=ptr_callback_head(off=0,imm=0) R6_w=ptr_task_struct(off=0,imm=0)
; func = work->func;
8: (79) r2 = *(u64 *)(r1 +8) ; R1_w=ptr_callback_head(off=0,imm=0) R2_w=scalar()
; if (!work && !func)
9: (4f) r1 |= r2
math between ptr_ pointer and register with unbounded min value is not allowed
below is insn 10 and 11
10: (55) if r1 != 0 goto +5
11: (18) r1 = 0 ll
...
In llvm, the code generation of 'r1 |= r2' happened in codegen
selectiondag phase due to difference of opaque pointer vs. non-opaque pointer.
Without [1], the related code looks like:
r2 = *(u64 *)(r6 + 2120)
r1 = *(u64 *)(r2 + 8)
if r2 != 0 goto +6 <LBB0_4>
if r1 != 0 goto +5 <LBB0_4>
r1 = 0 ll
...
I haven't found a good way in llvm to fix this issue. So let us workaround the
problem first so bpf CI won't be blocked.

Last cycle we extended the idmapped mounts infrastructure to support
idmapped mounts of idmapped filesystems (No such filesystem yet exist.).
Since then, the meaning of an idmapped mount is a mount whose idmapping
is different from the filesystems idmapping.
While doing that work we missed to adapt the acl translation helpers.
They still assume that checking for the identity mapping is enough. But
they need to use the no_idmapping() helper instead.
Note, POSIX ACLs are always translated right at the userspace-kernel
boundary using the caller's current idmapping and the initial idmapping.
The order depends on whether we're coming from or going to userspace.
The filesystem's idmapping doesn't matter at the border.
Consequently, if a non-idmapped mount is passed we need to make sure to
always pass the initial idmapping as the mount's idmapping and not the
filesystem idmapping. Since it's irrelevant here it would yield invalid
ids and prevent setting acls for filesystems that are mountable in a
userns and support posix acls (tmpfs and fuse).
I verified the regression reported in [1] and verified that this patch
fixes it. A regression test will be added to xfstests in parallel.

LLVM commit [1] changed loop pragma behavior such that
full loop unroll is always honored with user pragma.
Previously, unroll count also depends on the unrolled
code size. For pyperf600, without [1], the loop unroll
count is 150. With [1], the loop unroll count is 600.
The unroll count of 600 caused the program size close to
298k and this caused the following code is generated:
0: 7b 1a 00 ff 00 00 00 00 *(u64 *)(r10 - 256) = r1
; uint64_t pid_tgid = bpf_get_current_pid_tgid();
1: 85 00 00 00 0e 00 00 00 call 14
2: bf 06 00 00 00 00 00 00 r6 = r0
; pid_t pid = (pid_t)(pid_tgid >> 32);
3: bf 61 00 00 00 00 00 00 r1 = r6
4: 77 01 00 00 20 00 00 00 r1 >>= 32
5: 63 1a fc ff 00 00 00 00 *(u32 *)(r10 - 4) = r1
6: bf a2 00 00 00 00 00 00 r2 = r10
7: 07 02 00 00 fc ff ff ff r2 += -4
; PidData* pidData = bpf_map_lookup_elem(&pidmap, &pid);
8: 18 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 r1 = 0 ll
10: 85 00 00 00 01 00 00 00 call 1
11: bf 08 00 00 00 00 00 00 r8 = r0
; if (!pidData)
12: 15 08 15 e8 00 00 00 00 if r8 == 0 goto -6123 <LBB0_27588+0xffffffffffdae100>
Note that insn 12 has a branch offset -6123 which is clearly illegal
and will be rejected by the verifier. The negative offset is due to
the branch range is greater than INT16_MAX.
This patch changed the unroll count to be 150 to avoid above
branch target insn out-of-range issue. Also the llvm is enhanced ([2])
to assert if the branch target insn is out of INT16 range.

With the gcc driver now being more complete and describing clocks which
might not always be write-accessible to the OS, conservatively specify
all such clocks as protected in the SoC dts.
The board dts - or even user-supplied dts - can override this property
to reflect the actual configuration.

Add four clocks which need to be manipulated in order to initialize the AHB
bus which exposes the SCC block in the global address space.
If a device is known to be configured such that writing to these
registers from Linux is not permitted, the 'protected-clocks'
device tree property must be used to denote that fact.
