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: (32 commits) [libata] sata_mv: print out additional chip info during probe [libata] Use ATA_UDMAx standard masks when filling driver's udma_mask info [libata] AHCI: Add support for Marvell AHCI-like chips (initially 6145) [libata] Clean up driver udma_mask initializers libata: Support chips with 64K PRD quirk Add a PCI ID for santa rosa's PATA controller. sata_sil24: sil24_interrupt() micro-optimisation Add irq_flags to struct pata_platform_info sata_promise: cleanups [libata] pata_ixp4xx: kill unused var ata_piix: fix pio/mwdma programming [libata] ahci: minor internal cleanups [ATA] Add named constant for ATAPI command DEVICE RESET [libata] sata_sx4, sata_via: minor documentation updates [libata] ahci: minor internal cleanups [libata] ahci: Factor out SATA port init into a separate function [libata] pata_sil680: minor cleanups from benh [libata] sata_sx4: named constant cleanup [libata] pata_ixp4xx: convert to new EH [libata] pdc_adma: Reorder initializers with a couple structs ...
