[RESEND PATCH v6 00/14] drm/trace: Mirror DRM debug logs to tracefs

[Sean Paul]

From: Sean Paul <seanpaul at chromium.org>

Hi all,
I just had the pleasure of rebasing this set on our CrOS downstream
kernel and wanted to resend it for consideration once again. There
hasn't been any resistence to the set AFAIK, just perhaps not enough
motivation for anyone to hit the go bit. There was some interest from
the msm folks about a month ago, and it has been an invaluable tool
on CrOS for the past ~year. Hopefully someone can dig into this and
provide some feedback so we can move this forward.

Thanks!

Sean
