[PATCHv3 0/2] creating non-section aligned lowmem mappings

Hi,

I found problems when I reserved non-section aligned memory blocks
by the device tree. The problem is that the memblock_set_current_limit()
point to the first section aligned memblock in the
first place (sanity_check_meminfo), but the memblock may be split
into non-section aligned memblocks because the memblock_reserve() calls
in arm_memblock_init().


*** BLURB HERE ***

  arm: fix non-section-aligned low memory mapping
  arm: use max_lowmem_limit in find_limit()
