Alan Cox 0d53a17bde Fix a race involving vnode_pager_input_smlfs(). Specifically, in the case
that vnode_pager_input_smlfs() zeroes the page, it should not mark the page
as valid until after the page is zeroed.  Otherwise, the page could be
mapped for read access (e.g., by vm_map_pmap_enter()) before the page is
zeroed.  Reviewed by: tegge

Eliminate gratuitous clearing of the page's dirty mask by
vnode_pager_input_smlfs().  Instead, assert that the page is clean.
Reviewed by: tegge

Eliminate some blank lines.

Eliminate pointless calls to pmap_clear_modify() and vm_page_undirty() from
vnode_pager_input_old().  The page is not mapped.  Therefore, it cannot have
any page table entries that are modified.

Eliminate an incorrect comment from vnode_pager_generic_getpages().
