DMA contiguous allocations have been able to use highmem since commit "95b0e65 ARM: mm: don't limit default CMA region only to low memory" but a comment still notes the earlier "low memory" limitation. Update the comment to remove the low memory limitation and fix the s/contigouos/contiguous/ typo while we're at it. Signed-off-by: George G.
