Use statfs to determine size of huge pages
The current method of finding out the size of huge pages does not work
reliably anymore. Current Linux supports more than one huge page size
but /proc/meminfo only show one of the supported sizes.
To find out the real page size used can be found by calling statfs. This
patch changes qemu to use statfs instead of parsing /proc/meminfo.
