[PATCH 0/2][linux-yocto-3.2] fri2 serial port fixes for preempt-rt

[Darren Hart <dvhart@linux.intel.com>]

These patches address are lockup when attempting login over serial on the fri2
when running the preempt-rt kernel. I have sent the first patch out for review,
but have not yet heard back. The serial port works and appears fairly stable.
However, I would prefer to keep these patches in yocto/preempt-rt/fri2 until
they are merged upstream in their final form. Please apply to a new branch:

    yocto/preempt-rt/fri2
