[ARM] initrd: claim initrd memory exclusively
Claim the initrd memory exclusively, and order other memory reservations beforehand. This allows us to determine whether the initrd memory was overwritten, and disable the initrd in that case. This avoids a 'bad page state' bug. Tested-by: Ralph Siemsen <ralphs@netwinder.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
