ARM: 8394/1: update memblock limit after mapping lowmem
The memblock limit is currently used in find_limits
to find the bounds for ZONE_NORMAL. The memblock
limit may need to be rounded down a PMD size to ensure
allocations are fully mapped though. This has the side
effect of reducing the amount of memory in ZONE_NORMAL.
Once all lowmem is mapped, it's safe to change the memblock
limit back to include the unaligned section. Adjust the
memblock limit after lowmem mapping is complete.
Before:
# cat /proc/zoneinfo | grep managed
managed 62907
managed 424
After:
# cat /proc/zoneinfo | grep managed
managed 63331
