H A Dsysfs-firmware-efi-runtime-map926172d4 Fri Dec 20 04:02:18 CST 2013 Dave Young <dyoung@redhat.com> efi: Export EFI runtime memory mapping to sysfs

kexec kernel will need exactly same mapping for EFI runtime memory
ranges. Thus here export the runtime ranges mapping to sysfs,
kexec-tools will assemble them and pass to 2nd kernel via setup_data.

Introducing a new directory /sys/firmware/efi/runtime-map just like
/sys/firmware/memmap. Containing below attribute in each file of that
directory:

attribute num_pages phys_addr type virt_addr
