Shaohui Zheng ea0854170c memory hotplug: fix a bug on /dev/mem for 64-bit kernels
Newly added memory can not be accessed via /dev/mem, because we do not
update the variables high_memory, max_pfn and max_low_pfn.

Add a function update_end_of_memory_vars() to update these variables for
64-bit kernels.
