Merge branch 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:

 - a number of libata core changes to better support NCQ TRIM.

 - ahci now supports MSI-X in single IRQ mode to support a new
   controller which doesn't implement MSI or INTX.

 - ahci now supports edge-triggered IRQ mode to support a new controller
   which for some odd reason did edge-triggered IRQ.

 - the usual controller support additions and changes.
