Make sure that highmem pages are not added to symlink page cache
inode_nohighmem() is sufficient to make sure that page_get_link() won't try to allocate a highmem page. Moreover, it is sufficient to make sure that page_symlink/__page_symlink won't do the same thing. However, any filesystem that manually preseeds the symlink's page cache upon symlink(2) needs to make sure that the page it inserts there won't be a highmem one. Fortunately, only nfs and shmem have run afoul of that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
