Nit: thi
Provide a wrapper function to be used by kernel code to check whether
a crash kernel is loaded. It returns the same value that can be seen
in /sys/kernel/kexec_crash_loaded by userspace programs.
I'm exporting the function, because it will be used by Xen, and it is
possible to compile Xen modules
