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 4dce8ba94c75 ("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 803739d25c23 ("[libata]
replace sata_settings with devslp_timing")
5) Fix regression impacting SMART and smartd, broken by commit
84a9a8cd9d0a ("[libata] Set proper SK when CK_COND is set")"
* tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev:
[libata] Fix HDIO_DRIVE_* ioctl() Linux 3.9 regression
libata: fix DMA to stack in reading devslp_timing parameters
ata_piix: Fix DVD not dectected at some Haswell platforms
libata: Set max sector to 65535 for Slimtype DVD A DS8A8SH drive
