Log Message:
Pull up following revision(s) (requested by hgutch in ticket #1588):
sys/arch/sparc64/include/vmparam.h: revision 1.43
Avoid using (1<<64)-1 for VM_MAX{,USER}_ADDRESS as rounding that up to
the next page boundary gives 0 and instead make the VA space end one
page earlier.
Fixes PR sparc64/57219.
