arch/powerpc/platforms/pseries/hotplug-memory.c: section removal cleanups
Followups to d760afd4d257 ("memory-hotplug: suppress "Trying to free nonexistent resource <XXXXXXXXXXXXXXXX-YYYYYYYYYYYYYYYY>" warning"). - use unsigned long type, as overflows are conceivable - rename `i' to the less-misleading and more informative `section' Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
