Or not. ;-) This commit breaks boot on my MacBookAir3,1:

commit 8d57470d8f859635deffe3919d7d4867b488b85a

x86, mm: setup page table in top-down

Get pgt_buf early from BRK, and use it to map PMD_SIZE from top at first.
Then use mapped pages to map more ranges below, and keep looping until
all pages get mapped.

Being a 64-bit apple-EFI machine, it probably runs through an obscure
path in this patch. I wish I had more vital information, but I get the
white screen of death, so not much to go on so far.
