Christoph Lameter 0ffe984917 [IA64] Prefetch mmap_sem in ia64_do_page_fault()
Take a hint from an x86_64 optimization by Arjan van de Ven and use it
for ia64.  See a9ba9a3b38

Prefetch the mmap_sem, which is critical for the performance of the page fault
handler.

Note: mm may be NULL but I guess that is safe.
