Update of /cvsroot/src/sys/arch/alpha/alpha
In directory nb00:/tmp/cvs-serv25330

Modified Files:
	pmap.c 
Log Message:
Give pmap_collect() some substance: when called, a process is being
swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.

Since the pmap module is allowed to "forget" mappings, pmap_collect()
may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.
