Nick,

fuse and reiser4 still use __grab_cache_page() although your patch
removed it:

build-r7257.out:/local/linsrc/tmp/mmotm-2008-1216-0043/fs/reiser4/plugin/file/file_conversi
on.c:689: error: implicit declaration of function '__grab_cache_page'

whose patch is that?

If CONFIG_SPARSE_IRQ is not enabled, then builds fail with:

build-r7248.out:/local/linsrc/tmp/mmotm-2008-1216-0043/kernel/irq/handle.c:434: error: 'irq_desc_lock_class' undeclared (first use in this function)
