against regular memory accesses.
Ok, so it at least boots on x86-32. Thus probably on x86-64 too (since

I applied this on top of the git pull from
/kernel/mca_asm.S and the
position of the percpu data.
Is my analysis correct? Do you like my fix and does the patch build and
boot on your system? Thanks,
