This is a resend of the patches originally posted here:


I received some minor comments in that thread, but nothing that warranted
any changes to the code. Due to the nature of these changes, I would
very much like to put these into -next for some exposure prior to merging.

Again, all feedback welcome.


Will Deacon (3):
  ARM: mm: remove IPI broadcasting on ASID rollover
  ARM: mm: avoid taking ASID spinlock on fastpath
  ARM: mm: use bitmap operations when allocating new ASIDs
