Use real time pcp locking for page draining during cpu unplug
Looks like a merging mistake that happened at some point. This
is the only place in the file that disables interrupts directly.
This fixes one case of CPU hotunplug failing on RT, but there
are still more.

On AT91 David Brownell noticed several months
ago that the DBGU can miss some characters on NO_HZ. I would expect
that this would be better now due to the shorter interrupt handler,
although it was not my goal to solve it with these patches.
The current (kernel.org git) AT91
In that case, shall I create a new patchset for this compared to mainline?
Then we can merge the DMA patch in the interrupt handler later on. (it
is really difficult to do)
Oops, Typo, I meant: it is NOT really difficult...
