thorpej 42c671ffba Modify uvm_map_pageable() and uvm_map_pageable_all() to follow POSIX 1003.1b ... semantics. That is, regardless of the number of mlock/mlockall calls, an munlock/munlockall actually unlocks the region (i.e. sets wiring count to 0). Add a comment describing why uvm_map_pageable() should not be used for transient page wirings (e.g. for physio) -- note, it's currently only (ab)used in this way by a few pieces of code which are known to be broken, i.e. the Amiga and Atari pmaps, and i386 and pc532 if PMAP_NEW is not used. The i386 GDT code uses uvm_map_pageable(), but in a safe way, and could be trivially converted to use uvm_fault_wire() instead.		1999-06-16 19:34:24 +00:00
