This patch series collects a number of fixes centered
around improving the AHCI device.
A number of them used to be tied to as-yet unposted
ahci-test patches, but I have separated them out
in order to post them standalone and collect feedback.
This series as a whole fixes a number of crashes,
bugs, and some specification issues that were a problem
mostly in unit testing, though several observable
problems with real guests are fixed by this series:
(1) Byte count after DMA completion fixes Windows 7
hibernate as well as non-ncq BSODs.
(2) FIS decomposition fixes prevent corruption when
reading from / writing to sectors located beyond
the LBA28 limit.
(Reported by Eniac Zhang <en...@hp.com>)
(3) SDB_FIS construction issues may be partly responsible
for unreliable NCQ operation within windows.
