[GIT PULL] libata changes for v3.18-rc1

From: Tejun Heo

Hello, Linus.

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.

Thanks.
