[PATCH v2 00/12] drm/panfrost: Misc fixes/improvements

[Boris Brezillon]

Hello,

Sorry for the noise, but I forgot 2 fixes (one fixing the error
set to the sched fence when the driver fence allocation fails,
and the other one shrinking the dma signalling section to get
rid of spurious lockdep warnings).

The rest of the series hasn't changed.

The first patch has been submitted a while ago but was lacking a way
to kill in-flight jobs when a context is closed; which is now addressed
in patch 10.

The rest of those patches are improving fault handling (with some code
refactoring in the middle).

"drm/panfrost: Do the exception -> string translation using a table"
still has a TODO. I basically mapped all exception types to
EINVAL since most faults are triggered by invalid job/shaders, but
there might be some exceptions that should be translated to something
else. Any feedback on that aspect is welcome.

Regards,

Boris
