Merge branch 'for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata update from Tejun Heo: "AHCI is getting per-port irq handling and locks for better scalability. The gain is not huge but measureable with multiple high iops devices connected to the same host; however, the value of threaded IRQ handling seems negligible for AHCI and it likely will revert to non-threaded handling soon. Another noteworthy change is George Spelvin's "libata: Un-break ATA blacklist". During 3.17 devel cycle, the libata blacklist glob matching got generalized and rewritten; unfortunately, the patch forgot to swap arguments to match the new match function and ended up breaking blacklist matching completely. It got noticed only a couple days ago so it couldn't make for-3.17-fixes either. :( Other than the above two, nothing too interesting - the usual cleanup churns and device-specific changes" * 'for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (22 commits) pata_serverworks: disable 64-KB DMA transfers on Broadcom OSB4 IDE Controller libata: Un-break ATA blacklist AHCI: Do not acquire ata_host::lock from single IRQ handler AHCI: Optimize single IRQ interrupt processing AHCI: Do not read HOST_IRQ_STAT reg in multi-MSI mode AHCI: Make few function names more descriptive AHCI: Move host activation code into ahci_host_activate() AHCI: Move ahci_host_activate() function to libahci.c AHCI: Pass SCSI host template as arg to ahci_host_activate() ata: pata_imx: Use the SIMPLE_DEV_PM_OPS() macro AHCI: Cleanup checking of multiple MSIs/SLM modes libata-sff: Fix controllers with no ctl port ahci_xgene: Fix the error print invalid resource for APM X-Gene SoC AHCI SATA Host Controller driver. libata: change ata_<foo>_printk routines to return void ata: qcom: Add device tree bindings information ahci-platform: Bump max number of clocks to 5 ahci: ahci_p5wdh_workaround - constify DMI table libahci_platform: Staticize ahci_platform_<en/dis>able_phys() pata_platform: Remove useless irq_flags field pata_of_platform: Remove "electra-ide" quirk ...
