6af61a7614a306fe882a0c2b4ddc63b65aa66efc 'x86: clean up max_pfn_mapped
usage - 32-bit' makes the following comment:
XEN PV and lguest may need to assign max_pfn_mapped too.
But no CC. Yinghai, wasting fellow developers' time is a VERY bad
habit. If you do it again, I will hunt you down and try to extract
the three hours of my life I just lost :)
