Subject: fix update_mmu_cache in fremap.c
From: Hugh Dickins <hugh@xxxxxxxxxxx>
There are two calls to update_mmu_cache in fremap.c, both defective.
The one in install_page needs to be accompanied by lazy_mmu_prot_update
(some other cleanup time, move that into ia64 update_mmu_cache itself); and
the one in install_file_pte should be removed since the pte is not present.
