[PATCH] Add a sysfs file to determine if a kexec kernel is loaded

Browse source

Create two files in /sys/kernel, kexec_loaded and kexec_crash_loaded.  Each
file contains a simple boolean value indicating whether the relevant kernel
has been loaded into memory.  The motivation for this is geared around
support.
