ARM: 8637/1: Adjust memory boundaries after reservations
commit 985626564eedc470ce2866e53938303368ad41b7 upstream.
adjust_lowmem_bounds is responsible for setting up the boundary for
lowmem/highmem. This needs to be setup before memblock reservations can
occur. At the time memblock reservations can occur, memory can also be
removed from the system. The lowmem/highmem boundary and end of memory
may be affected by this but it is currently not recalculated. On some
systems this may be harmless, on others this may result in incorrect
ranges being passed to the main memory allocator. Correct this by
recalculating the lowmem/highmem boundary after all reservations have
been made.
