[Intel-gfx] [PATCH 00/15] pipelined fencing

[Daniel Vetter]

Hi all,

After I've found out why suddenly both my intel boxes refused to boot (hint
CONFIG_NO_BOOTMEM=y is evil) I can patch-bomb intel-gfx again ;)

The first part of the series (patches 1 -9) is a pure cleanup and I think
worth it on its own. The rest introduce needed infrastucture to track
pipelined fence usage, finally enabling pipelined fencing with the last
patch.

Essentially too many changes since the rfc to summarize them with anything
else than "now it seems to actually work". Individual patches contain
detailed changelogs.

I've been running this series essentially unchanged (save some rebases) on
various kernels for the past few weeks on my i855 and i945. Doesn't seem to
have any ill effects.

Comments higly welcome.

Yours, Daniel
