Modified Files:
	syssrc/sys/arch/alpha/alpha: machdep.c pmap.c

Log Message:
The Alpha pmap_virtual_space() can return compile-time constants,
so do so.  This allows us to call uvm_pageboot_alloc() before
pmap_bootstrap().

Also, the virtual_start variable is unneeded in the Alpha pmap
module, and virtual_end (and the mostly-unused-except-by-bus_dma
variables avail_start and avail_end) can be `computed' at the
same time.
