#     powerpc/fadump: re-register firmware-assisted dump if already registered
#     
#     Firmware-Assisted Dump (FADump) needs to be registered again after any
#     memory hot add/remove operation to update the crash memory ranges. But
#     currently, the kernel returns '-EEXIST' if we try to register without
#     uregistering it first. This could expose the system to racing issues
#     while unregistering and registering FADump from userspace during udev
#     events. Spare the userspace of this and let it be taken care of in the
#     kernel space for a simpler interface.
#     
#     Since this change, running 'echo 1 > /sys/kernel/fadump_registered'
#     would result in re-regisering (unregistering and registering) FADump,
#     if it was already registered.
