Great, will give it a try hopefully tomorrow. Sounds like that's the way to deal with fixing up things when booting up older UP ARMv6 without the 32v6 support :)
What I've also been debating about is adding another word to the smpalt structure, that being a set of flags which denote the situation where the alternative should be used.
That means we can use it to do individual word replacements for SMP vs UP, ARMv6 vs ARMv6k etc.
Sounds good to me. Maybe it should then be called cpualt instead of smpalt?
Tried booting your patch and needed the following fix for Cortex-A8 UP.
Now it boots to the following error:
Machine configuration botched (nr -1073741824), unable to continue.
Does some struct size need to be changed or something?
Regards,
Tony
