Log Message:

Several changes, developed and tested concurrently:
* Provide POSIX 1003.1b mlockall(2) and munlockall(2) system calls.
  MCL_CURRENT is presently implemented.  MCL_FUTURE is not fully
  implemented.  Also, the same one-unlock-for-every-lock caveat
  currently applies here as it does to mlock(2).  This will be
  addressed in a future commit.
* Provide the mincore(2) system call, with the same semantics as
  Solaris.
* Clean up the error recovery in uvm_map_pageable().
* Fix a bug where a process would hang if attempting to mlock a
  zero-fill region where none of the pages in that region are resident.
  [ This fix has been submitted for inclusion in 1.4.1 ]
