src/sys/arch/mips/mips: mips_mcclock_loop.S
Log Message:
Revert 0(sp) -> CALLFRAME_S0(sp) changes in rev 1.4.
0(sp) is safe here even on O32 because the only callee function
mips_cp0_cause_read() doesn't take arguments, but it's caller's
responsibility to choose proper stackframe region and the name
of CALLFRAME_S0 is just confusing. No binary change.
