This patch series adds a new interface /sys/firmware/memmap to export
the BIOS (Firmware) provided memory map via sysfs for usage with
While the first patch adds the generic interface, the second patch
implements that interface for E820 on x86.
Change compared to previous commit:
1. Added Greg KH to Cc as suggested by H. Peter Anvin to review sysfs
2. Display the configuration option only if CONFIG_EMBEDDED is set.
If not, default to including the code in any case as it is not only
useful for kexec.
