Merge branch 'for-4.5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo:
- PORTS_IMPL workaround for very early ahci controllers is misbehaving
on new systems. Disabled on recent ahci versions.
- Old-style PIO state machine had a horrible locking problem. Don't
know how we've been getting away this far. Fixed.
- Other device specific updates.
