CVS commit: src/sys/uvm

[Matt Thomas <matt%netbsd.org@localhost>]

Module Name:    src
Committed By:   matt

Modified Files:
        src/sys/uvm: uvm_glue.c

Log Message:
Only swapout uareas if VMSWAP_UAREA is defined (which is should be by default).
If it's not defined and PMAP_MAP_POOLPAGE is defined and USPACE == PAGE_SIZE,
then allocate/map USPACE via uvm_pagealloc/PMAP_MAP_POOLPAGE.

On platforms like MIPS with 16KB pages, this means that uareas (and hence lwp
kernel stacks) will be always be accessible since they will be KSEG0.
