Subject: [4.4] broken conversion from efi to kernel page table

This fixes boot panics, hangs which I reported in this thread:

http://lkml.iu.edu/hypermail/linux/kernel/1801.1/00951.html

I have not yet verified if similar issue is applicable to newer
kernels.

Re-sending it as a proper git send-email submission.
