This series starts by converting the last easy kmap() uses to
kmap_local_page().

There is one more call to kmap() wrapped in ttm_bo_kmap_ttm().  Unfortunately,
ttm_bo_kmap_ttm() is called in a number of different ways including some which
are not thread local.  I have a patch to convert that call.  However, it is not
straight forward so it is not included in this series.

The final 2 patches fix bugs found while working on the ttm_bo_kmap_ttm()
conversion.


Ira Weiny (7):
drm/i915: Replace kmap() with kmap_local_page()
drm/amd: Replace kmap() with kmap_local_page()
drm/gma: Remove calls to kmap()
drm/radeon: Replace kmap() with kmap_local_page()
drm/msm: Alter comment to use kmap_local_page()
drm/amdgpu: Ensure kunmap is called on error
drm/radeon: Ensure kunmap is called on error

Gentile ping on this series?  Will it make this merge window?

Thanks,

I think this fell through the cracks and so no. Note that generally we
feature-freeze drm tree around -rc6 anyway for the upcoming merge window,
so you were cutting this all a bit close anyway. Also looks like the ttm
kmap caching question didn't get resolved?

Anyway if patches are stuck resend with RESEND and if people still don't
pick them up poke me and I'll apply as fallback.

Cheers, Daniel

Ok, No problem.  I just had not heard if this was picked up or not.

I'm sorry I thought it was resolve for this series.  Christian said the patches
in this series were "a good bug fix" even if not strictly necessary.[1]  Beyond
this series I was discussing where to go from here, and is it possible to go
further with more changes.[2]  At the moment I don't think I will.

Christian did I misunderstand?  I can drop patch 6 and 7 if they are not proper
bug fixes or at least clarifications to the code.

Yeah, it is indeed a correct cleanup. I would just *not* put a CC stable 
on it because it doesn't really fix anything.

Ok can you pls get the amd/radeon ones stuffed into alex' tree? Or do we
want to put all the ttm ones into drm-misc instead?
