1) Fix ATAPI regression, noticed mainly on tape drives, due to a commit

which mistakenly changed an 'int' return type to a 'bool'.  Broken
    by 4dce8ba94c.
 
 2) Add Slimtype DVD A DS8A8SH ATAPI quirk
 
 3) ata_piix: Intel Haswell platform quirk
 
 4) Avoid DMA'ing to stack buffer, when obtaining DEVSLP timings.
    IMO a mild regression, given that libata previously did not DMA to a stack
    buffer.  Broken by 803739d2.
 
 5) Fix regression impacting SMART and smartd, broken by 84a9a8cd9.

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

Pull libata fixes from Jeff Garzik:
 "The HDIO_DRIVE_* fix is really the biggie.

  1) Fix ATAPI regression, noticed mainly on tape drives, due to a
     commit which mistakenly changed an 'int' return type to a 'bool'.
     Broken by commit 4dce8ba94c ("libata: Use 'bool' return value for
     ata_id_XXX")

  2) Add Slimtype DVD A DS8A8SH ATAPI quirk

  3) ata_piix: Intel Haswell platform quirk

  4) Avoid DMA'ing to stack buffer, when obtaining DEVSLP timings.  IMO
     a mild regression, given that libata previously did not DMA to a
     stack buffer.  Broken by commit commit 803739d25c ("[libata]
     replace sata_settings with devslp_timing")

  5) Fix regression impacting SMART and smartd, broken by commit
     84a9a8cd9d ("[libata] Set proper SK when CK_COND is set")"
