[PATCH 0/2] Small fixes to memblock and nobootmem

From: Philipp Hachtmann
Date: Tue Jan 07 2014 - 10:17:01 EST

While working on the conversion of the s390 port to use memblock and
nobootmem instead of bootmem I discovered two small bugs:

alloc_memory_core_early() in mm/nobootmem.c called memblock_reserve()
without forwarding the return value of memblock_reserve().

free_low_memory_core() (used by free_all_bootmem) in mm/nobootmem.c
already took care of releasing the memblock.reserved array in case
it has been allocated using memblock itself. This behaviour was
missing for memblock.memory.
Cases where memblock.memory grows bigger than the initial 128 entries
have been seen. So this should be supported as well.

Philipp Hachtmann (2):
mm, nobootmem: Add return value check in __alloc_memory_core_early()
mm: free memblock.memory in free_all_bootmem
