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:

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
----------------------------------------------------------------
