Log message:
Add retguard to macppc kernel locore.S, ofwreal.S, setjmp.S
This changes RETGUARD_SETUP(ffs) to RETGUARD_SETUP(ffs, %r11, %r12)
and RETGUARD_CHECK(ffs) to RETGUARD_CHECK(ffs, %r11, %r12)
to show that r11 and r12 are in use between setup and check, and to
pick registers other than r11 and r12 in some kernel functions.
