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 structure. 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. Please review! Signed-off-by: Bernhard Walle
