[PATCH v2 0/4] ahci: misc fixes/tests for 2.4
[PATCH v2 00/16] ahci: ncq cleanup, part 1
This chunk gets NCQ migration and and resume support working.
There's still some left to do, particularly around error handling
and FIS semantics, but this should get us most of the way there.

01: Fixed limit parameter to int32_t to match existing implicit cap
Removed is_write parameter. Nobody used it.
Implemented PRD limit for BMDMA
06: Squashed what was patch 06/07.
Adjusted where we clear ncq_tfs->halt.
11: Fixed port/slot bounds checking
Removed ncq_tfs section from ahci_state_post_load
moved ahead of what's now #12.
12: Picked up the truncated sections from what's now #11
Rely on get_cmd_header to do more error checking for us.
16: Comment explaining the IRQ mechanics for SDBFIS.
