PS: please note that Oak's e-mail has changed.
No invocation of get_user_pages() uses the vmas parameter, so remove
it.
The GUP API is confusing and caveated. Recent changes have done much to
improve that, however there is more we can do. Exporting vmas is a prime
target as the caller has to be extremely careful to preclude their use

It is likely Height was expected here, instead of Width.
Test the correct variable.

Sorry, I found that the latest code function has become amdgpu_cs_pass1,
and radeon_cs_parser_init has the same problem.And i will send the patch.

Hello,
I am going to file a security bug.
VULNERABILITY DETAILS
ioctl$AMDGPU_CS will call amdgpu_cs_ioctl which will call
amdgpu_cs_parser_init. The type of size is unsigned(4 bytes)[1]. And size
is assigned from p->chunks[i].length_dw[2] which is assigned from
user_chunk.length_dw[3], which
It is likely p1_min_meta_chunk_bytes was expected here, instead of
min_meta_chunk_bytes.
Test the correct variable.

[Why]
The selfring doorbell aperture will change when we resize
FB BAR successfully during gmc sw init, we should reorder
the sequence of enabling doorbell selfring aperture.
[How]
Move enable_doorbell_selfring_aperture from *_common_hw_init
to *_common_late_init.
This fixes the potential issue
[Why & How]
The sequence for collecting down_reply/up_request from source
perspective should be:
Request_n->repeat (get partial reply of Request_n->clear message ready
flag to ack DPRX that the message is received) till all partial
replies for Request_n are received->new Request_n+1.
