[PATCH 0/3] Use FAST_REQUEST mechanism for non-blocking H2G calls

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The GuC interface supports a mechanism for returning errors against
non-blocking H2G calls. This is called FAST_REQUEST. Given that the
call is asynchronous, matching the returned error up is difficult.
However, getting any error at all back is better than no error.

If any such errors are reported, then extra tracking support can be
compiled in for manual debug.
