lguest: set max_pfn_mapped, growl loudly at Yinghai Lu
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 :) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Yinghai Lu <yhlu.kernel@gmail.com>
