4057b0210c 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.

08726c6d9b 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.

0c24a80ae8 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.

0cdd391c05 New ISA specific PCI code.

6e667246cd 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 !

8772a34db1 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

fd40ec89df 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.)

390bfe9b40 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.

a62ef20881 Moved call to vnode_pager_uncache in rename() to before the VOP_RENAME. 
It was previously after the VOP_RENAME and the reference and lock on
the vnode had already been lost, allowing interesting internel
inconsistencies. This is one of the two reasons why freefall was crashing
every hour or two (the other being nullfs bugs).
Don't call vnode_pager_uncache in revoke(). revoke() is only allowed on
VCHR and VBLK vnodes.
