[PATCH 0/2] vmalloc: Introduce vmap_file()

["Vishal Moola (Oracle)" <vishal.moola@gmail.com>]

Currently, users have to call vmap() or vmap_pfn() to map pages to
kernel virtual space. vmap() requires the page references, and
vmap_pfn() requires page pfns. If we have a file but no page references,
we have to do extra work to map them.

Create a function, vmap_file(), to map a specified range of a given
file to kernel virtual space. Also convert a user that benefits from
vmap_file().
