src/sys/arch/pmax/pmax: locore_machdep.S
Log Message:
Use CALLFRAME_SP(sp) instead of CALLFRAME_S0(sp) to save s0.
At least PROM's _getenv() on 3MIN doesn't preserve CALLFRAME_S0(s0)
and prom_findcons() returns bogus console after mips64 merge.
XXX: I wonder if it's safe to use CALLFRAME_S0(sp) (== 0(sp)) on O32/O64..
