Another datapoint, just tried a 3.0.0-rc1 kernel, good news is that it
boots. Maybe the "x86, efi: Merge contiguous memory regions of the same
type" helps with these large number of maps?

However, there seems to be something else wrong as I get several "BUG:
Bad page state in process swapper pfn:00000" which have efi functions
on the stack, see dmesg output.
