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 libata: Use integer return value for atapi_command_packet_set
