[PATCH 2/2] arm64: mm: make pfn always valid with flat memory

2016-04-05 Thread Chen Feng
Make the pfn always valid when using flat memory. If the reserved memory is not align to memblock-size, there will be holes in zone. This patch makes the memory in buddy always in the array of mem-map. Signed-off-by: Chen Feng Signed-off-by: Fu Jun --- arch/arm64/mm/init.c | 7 --- 1 file
