f5cf85d40a Removed unused fifth argument to vm_object_page_clean(). Fixed bug with 
VTEXT not always getting cleared when it is supposed to. Added check to
make sure that vm_object_remove() isn't called with a NULL pager or for
a pager for an OBJ_INTERNAL object (neither of which will be on the hash
list). Clear OBJ_CANPERSIST if we decide to terminate it because of no
resident pages.

efea4e5256 Fixes and improvements from John Dyson: 
Fixed the I/O statistics
Allow WD1007 type controllers to work
Support MULTI-BLOCK I/O
Correct delay to use port 0x84, reading the status register
	might not be a long enough delay.
Changed probe message to match SCSI type devices.

c419d77e29 Added a check for wrong object size; print a warning, but deal with it 
correctly. The warning will tell us that there is a bug somewhere else
in sizing the object correctly.

8f4e17d4b2 Fixed bug in vm_mmap() where the object that is created in some cases 
was the wrong size. This is the likely cause of panics reported by
Lars Fredriksen and Paul Richards related to a -1 blkno when paging
via the swap_pager.

5b3f532eb1 New ISA specific PCI code. 
Supports shared PCI interrupts.

8673e05a9a Completely new PCI code: 
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

bc9ad24756 Disallow non page-aligned file offsets in vm_mmap(). We don't support this 
in either the high or low level parts of the VM system. Just return EINVAL
in this case, just like SunOS does.

f550a707bd Added a new version of trap_pfault() that disallows kernel page faults 
to the user address space unless pcb_onfault is set. The code is currently
commented out because iBCS2 and process debugging parts of the kernel
need to be changed/fixed first.

superseding the `nextchild' hack.  This also provides a way
forward to fix RTM_CHANGE and RTM_ADD as well.

69244b69db Support for pseudo-device LKMs. Note that this is restricted to only 
one pseudo per module (a restriction which will eventually be lifted) and
isthus not in its final form.

20e8807c09 This should be splimp() rather than splnet() since ifaddrs might go away

9b626c29f7 Fix race conditions involved in setting IP multicast options. This should 
fix Dennis Fortin's problem for good, if I've got it figured out right.

(The problem was that a `struct ifaddr' could get deleted out from under
the current requester, thus leaving him with an invalid interface pointer
and causing even more bogus accesses.)

ff769afc81 Don't attempt to sync pages in the V_SAVE case of vinvalbuf; doing so can

c01a9b8ca0 Incorporated 4.4-lite vnode_pager_uncache() and vnode_pager_umount() 
routines (and merged local changes). The changed vnode_pager_uncache
gets rids of the bogosity that you can call the routine without
having the vnode locked. The changed vnode_pager_umount properly locks
the vnode before calling vnode_pager_uncache.
