Merge tag 'efi-urgent' into x86/urgent
* 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
