[GIT PULL] EFI urgent fixes

[Matt Fleming]

Folks,

Please consider pulling the following fixes.

The first two are releated to the bug report I got from Linus and Josh
Boyer, whereby Fedora20 + grub2 systems were no longer booting. Linus
reverted the offending commit that broke grub2 boot, but that left us in
a state where Macbooks still didn't boot with EFI. This is fixed with
the below revert and I'm dropping a noisey boot time efi_printk() based
on Josh's request and Linus' OK.

The third patch fixes a 32-bit EFI boot stub bug where garbled text is
displayed on the screen if any of the efi_printk() statements run.

The following changes since commit 3eddc69ffeba092d288c386646bfa5ec0fce25fd:

  x86 early_ioremap: Increase FIX_BTMAPS_SLOTS to 8 (2014-09-14 15:24:31 +0100)
