CVS commit: src/sys/arch/alpha

["Jason R Thorpe" <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej

Modified Files:
        src/sys/arch/alpha/alpha: pmap.c vm_machdep.c
        src/sys/arch/alpha/include: pmap.h

Log Message:
Move the pointer to the pmap's lev1map out of the shared pmap structure
and into each CPU's pmap_percpu area.  This pointer is constant for the
life of the pmap, and moving it gives us an additional 8 bytes in the
shared pmap structure.

Because the kernel pmap does not have per-CPU data, all places where we
need the kernel pmap's lev1map now just reference kernel_lev1map directly.
