Module Name:    src
Committed By:   jdolecek

Modified Files:
        src/sys/dev/ic [jdolecek-ncq]: ahcisata_core.c ahcisatareg.h
            ahcisatavar.h

Log Message:
update error handling:
- switch to ata_timeout()
- stop using ch_status/ch_error for passing state/error, stop setting
  ATACH_IRQ_WAIT in ch_flags; pass the state via the last parameter
  to c_intr() routine
- add NCQ recovery and KILL_REQUEUE
- only call atastart() in c_intr() if there was no error

ahcisata-specific tweaks:
- add some handling for PM in the error recovery using FBS register,
  according to spec it should be independant of actual FBSS feature; untested
  as my hw doesn't support PM
