Merge branch 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev

* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev:
  libata: kill ATA_HORKAGE_DMA_RW_ONLY
  libata: use PIO for non-16 byte aligned ATAPI commands
  libata: call ata_check_atapi_dma() with qc better prepared
  libata: fix infinite EH waiting bug
  libata: fix ata_dev_disable()
  pata_it821x: fix section mismatch warning
  libata: remove unused variable from ata_eh_reset()
  libata: be less verbose about hpa
  libata: kill non-sense warning message
  libata: kill the infamous abnormal status message
  HPT374 is UDMA100 not UDMA133
