Log Message:
Infrastructure for lazy istream sync in the pmap module:
- Add a bitmask for the CPUs which need an isync before this pmap returns
  to userspace on that CPU.
- Define PMAP_USERRET(), a utility macro for userret() to use to process
  the deferred isync, and call it as appropriate in userret().
