So we this patch 
  http://lkml.iu.edu/hypermail/linux/kernel/1602.2/02637.html

sitting in -RT. Then someone posted
  http://www.spinics.net/lists/linux-rt-users/msg14975.html
which depends on it.
Before I was are of the first patch, I posted
  http://www.spinics.net/lists/linux-rt-users/msg14666.html

and nobody seems to care if anything of this gets merged upstream
where it belongs. Could some please carry this to Greg upstream?
