Michel Thierry Nov. 11, 2014, 4:47 p.m. UTC 
Following the legacy ring submission example, update the
ring->init_context() hook to support the execlist submission mode.

v2: update to use the new workaround macros and cleanup unused code.
This takes care of both bdw and chv workarounds.

v2.1: Add missing call to init_context() during deferred context creation.

v3: Split init_context (emit) in legacy/lrc modes. For lrc, get the ringbuf
from the context (Mika/Daniel).

v4: Merge init_context interfaces back, the legacy mode only needs the ring,
but the lrc mode needs the ring and context (Mika).

Issue: VIZ-4092
Issue: GMIN-3475

Cool, revised version already on the m-l, pls ignore my other reply ;-)

One nitpick for the future: We align continuation lines for paramter lists
to the opening (. checkpatch.pl --strict will catch this for you. I've
fixed this while applying since it disturbed my ocd too much ;-)
