high_memory defines upper bound on the directly mapped memory.
This bound is defined by the beginning of ZONE_HIGHMEM when a system has
high memory and by the end of memory otherwise.
All this is known to generic memory management initialization code that
can set high_memory while initializing core mm structures.
Remove per-architecture calculation of high_memory and add a generic
version to free_area_init().
This patch appears to be causing breakage on a number of 32 bit arm
platforms, including qemu's virt-2.11,gic-version=3. Affected platforms
die on boot with no output, a bisect with qemu points at this commit and
those for physical platforms appear to be converging on the same place.
Can you share how this can be reproduced with qemu?
