At least I assume so. The wof.S and wuf.S cases would only execute after we've started userland, as that code is used to validate the user stack in the register window store area. Therefore it won't run unless PSR_PS is clear in %psr or there are user register windows in the cpu. Neither of which will be true during early boot. You should therefore be fine except for the bits in head_32.S which you'll need to use tests and branches for anyways. -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
