[POWERPC] Fix mem= handling when the memory limit is > RMO size
There's a bug in my cleaned up mem= handling, if the memory limit is larger than the RMO size we'll erroneously enlarge the RMO size. Fix is to only change the RMO size if the memory limit is less than the current RMO value. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
