Hello all,
I've drafted a man page for two glib functions that haven't been
documented by the man-pages project yet: get_phys_pages(3) and
get_avphys_pages(3).
This is my first whole file contribution, so I was hoping I could
get some suggestions/pointers before submitting the actual patch :).
I based it largely on get_nprocs(3) manual page.
