hugetlbfs read() support
Support for reading from hugetlbfs files. libhugetlbfs lets application
text/data to be placed in large pages. When we do that, oprofile doesn't
work - since libbfd tries to read from it.
This code is very similar to what do_generic_mapping_read() does, but I
can't use it since it has PAGE_CACHE_SIZE assumptions.
