    modmachine: Implement physical memory access using /dev/mem (Linux, etc). · 354d1752
    Paul Sokolovsky authored 
    This requires root access. And on recent Linux kernels, with
CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in
/proc/iomem can be accessed. The above compiled-time option can be
however overriden with boot-time option "iomem=relaxed".

This also removed separate read/write paths - there unlikely would
be a case when they're different.
