Linux 3.11 compat: Replace num_physpages with totalram_pages
num_physpages was removed by
torvalds/linux@cfa11e08ed39eb28a9eff9a907b20913020c69b5, so lets replace
it with totalram_pages.
This is a bug fix as much as it is a compatibility fix because
num_physpages did not reflect the number of pages actually available to
the kernel:
http://lkml.indiana.edu/hypermail/linux/kernel/0908.2/01001.html
Also, there are known issues with memory calculations when ZFS is in a
Xen dom0. There is a chance that using totalram_pages could resolve
them. This conjecture is untested at the time of writing.
