2f586e1b2c Undo last commit - not a bug, just duplicate code. PG_MAPPED and 
PG_WRITEABLE are already cleared by vm_page_protect().

57687b2e1f Backed out most of previous commit to go with backing out support for 
revoke() on non-device files.

73a6265d68 Go back to only supporting revoke() for bdevs and cdevs. It is very 
buggy for fifos, and no one seems to have investigated its behaviour
on other types of files.  It has been broken since the Lite2 merge
in rev.1.54.

e9583ef187 From the PR: 
I added a FICL_TRACE-conditioned trace facility based on "see".
It is ugly because words' functions are almost all static, and ficlExec,
where the trace has to be located, can't get their pointers. So, #ifdef
this staticization, and add most of see's body into ficlExec. Duplication
of code, uglyness, etc. But it is cleanly #ifdef'ed, and works like a
charm.

	It does not provide "step" facility, though, just trace. It is
tunable at run-time through "trace!". If anyone (most likely me :) ever
wants a step facility, I'll add it. Should be easy.

7dbf82dc13 Change all manual settings of vm_page_t->dirty = VM_PAGE_BITS_ALL 
to use the vm_page_dirty() inline.

    The inline can thus do sanity checks ( or not ) over all cases.

68af6d169b vm_map_split() used to dirty the page manually after calling 
vm_page_rename(), but never pulled the page off PQ_CACHE if it was on
    PQ_CACHE.  Dirty pages in PQ_CACHE are not allowed and a KASSERT was
    added in -4.x to test for this... and got hit.

    In -4.x, vm_page_rename() automatically dirties the page.  This commit
    also has it deal with the PQ_CACHE case, deactivating the page in that
    case.

f7f7a5d7ab From the PR: 
FICL's TYPE copies the counted string to HERE, as abial has
remarked. Answering to abial's question, this is NOT garanteed to have
enough space.
...
	We have dynamic memory. Even before memory-alloc got in, we
already had dynamic memory. Use it, then! (ficlMalloc is sysdep, so I
suppose that's why it was not used for TYPE; ficl is probably designed
to work without a working ficlFree).

e4542174b0 vm_pager_put_pages() is passed an rcval array to hold per-page return 
values.  The 'int' return value for the procedure was never used and
    not well defined in any case when there are mixed errors on pages, so
    it has been removed.  vm_pager_put_pages() and associated vm_pager
    functions now return void.

89600e8663 There was a situation where sendfile() might attempt to initiate I/O

377f9b28a6 Don't try to calculate B_CACHE for an NFS related bp that has a

c679ae39a8 biosdisk.c 
Implement a new variable 'root_disk_unit' which supersedes
	'num_ide_disks' and makes it possible to explicitly set the
	root device unit number regardless of type considerations.

bootinfo.c
	If we can't calculate a dev_t for the root disk, complain and
	don't proceed to boot with an invalid boot device.
