[PATCH 00/42] Improvements for IB handling V2

[Alex Deucher <alexander.deucher@amd.com>]

This set contains a number of bug fixes and cleanups for
IB handling that I worked on over the holidays.  The first
the patches from V1 are already reviewed, so I didn't include
them in V2.

Patches 1-24:
Removes the direct submit path for IBs and requires
that all IB submissions use a job structure.  This
greatly simplifies the IB submission code. V2 uses
GFP_ATOMIC when in reset.

Patches 26-42:
Split IB state setup and ring emission.  This keeps all
of the IB state in the job.  This greatly simplifies
re-emission of non-timed-out jobs after a ring reset and
allows for re-emission multiple times if multiple resets
happen in a row.  It also properly handles the dma fence
error handling for timedout jobs with adapter resets.
V2 fixes the set_q handling by saving the ring state in
the job and redetermining the offsets as the packet
stream is replayed.  Jobs whose IBs are skipped still
handle the set_q state properly so the re-emitted packet
streams are always coherent.
