I think it's slightly buggy still.
I think the X86_SUPPORTS_MEMORY_FAILURE thing should also have a
depends on X86_MCE
line, because we still depend on MCE.
And as you found out, there's also the sparsemem thing.
Don't make it one huge ugly thing, just split out the requirements like
depends on X86_MCE depends on !X86_NUMAQ depends on X86_64 || !SPARSEMEM
because I think the requirements are fairly independent, and it makes it easier to read (you could even comment each line on why _that_ particular issue needs to disable X86_SUPPORTS_MEMORY_FAILURE)
But yeah, with that, and some testing, please add my sign-off (or acked-by, if you end up changing the patch so much that it has little to do with my original one)
Linus
