Subject: [GIT PULL] EFI urgent fixes

Folks,

Here are two commits I've queued up from Dave. The first fixes the efi
earlyprintk code and the second fixes a bug where we were exporting the
EFI runtime mappings for use by kexec-tools, despite the fact that those
mappings were not persistent across kexec reboot.

The following changes since commit 47514c996fac5e6f13ef3a4c5e23f1c5cffabb7b:

  efi: Pass correct file handle to efi_file_{read,close} (2014-04-10 21:20:03 +0100)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-urgent

for you to fetch changes up to a3530e8fe980f756b823d451fe9243f26db95fa5:

  x86/efi: Do not export efi runtime map in case old map (2014-06-02 12:21:59 +0100)

----------------------------------------------------------------
 * Fix earlyprintk=efi,keep support by switching to an ioremap() mapping
   of the framebuffer when early_ioremap() is no longer available and
   dropping __init from functions that may be invoked after
   free_initmem() - Dave Young

 * We shouldn't be exporting the EFI runtime map in sysfs if not using
   the new 1:1 EFI mapping code since in that case the mappings are not
   static across a kexec reboot - Dave Young
