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.
