So far I found a few things: > - there is no idle_notifier_register in 32-bit x86 There used to be one, just needs to be readded. > - there is no oops_begin in 32-bit x86 > - register names are different (rip, cs) regs->rip -> instruction_pointer() ->cs just needs a similar macro > So it looks like giving 32-bit x86 the same machine check support as in > 64-bit is both feasible and desirable.
