A dmesg from Keith of a working kernel would be good since the most
interesting things are the EFI memory map and the E820 memory map.

At this late -rc stage I agree it makes sense to revert this. The
CONFIG_X86_32 oops that the patch fixes has been around for years and no
one seems to have encountered it (until now), whereas this new
regression is likely to affect many more users.

Looks like there are some macbook memory map funnies that still need to
be addressed...
