Subject: [GIT PULL] EFI urgent fix

Hi guys,

Please consider pulling the following urgent fix from Dave. It fixes an
earlyprintk=efi regression introduced in v3.16. Due to changes in the
early ACPI code we run out of early_ioremap slots when earlyprintk=efi
is specified on the command line, resulting in a hang during kernel
boot.

This patch is clearly a core x86 change, but since it is a fix for an
EFI code issue I picked it up in my urgent queue. Let me know if you'd
like to route this some other way.

The following changes since commit 0ceac9e094b065fe3fec19669740f338d3480498:
