Hi,

I picked up all the review tags from Peter and Moritz and addressed
Peter's comments.
Most patches are unchanged but I added the info Peter suggested/provided
to some commit messages.
The patches "tty: xuartps: Move request_irq to after setting up the HW",
"tty: xuartps: Improve sysrq handling" and "tty: xuartps: Remove
'_OFFSET' suffix from #defines" are new, implementing the suggestions
Peter made in the v3 review (https://lkml.org/lkml/2015/11/21/172).
I pretty much rewrote "tty: xuartps: Refactor IRQ handling" (was: "tty:
xuartps: Only handle RX IRQs when RX is enabled"). Instead of adding a
flag, we now disable/enable the RX interrupts together with the
receiver. That should prevent the RX lock ups I saw.

	Thanks,
	S?ren
