This change made it into v6.12-rc1 as 68e599db7a54 ("drm/amdkfd:
Validate user queue buffers"). A Debian user (Dieter Faulbaum, on Cc)
reported that this change introduced a regression using a gfx803 device
resulting in a HSA exception when e.g. darktable is used. I didn't even
try to understand the problem, but maybe one of you have an idea about
the issue?!
