ca2be56ff9 Override the default VFS LKM dispatch functions so that a module 
unload function can be provided (this is necessary to unregister
the at_exit handler).

72c36e1413 Fix pmap_enter_quick() to stop it hanging when the level 2 pte exists 
but isn't valid.

Reimplement pmap_remove() to be much more efficient at removing large
stretches of addresses.

As part of reimplementing pmap_remove() fix pmap_protect() so that it stands
a hope of working.

9294f850e8 Don't return an error if the magic number is not present.

df9efa9a8b On the alpha, ports may be allocated above 64k. 
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386.  This is a stopgap with a
hopefully limited lifetime.

time since 4.4BSD lite.

7cb743ae28 Initialize more defaults for the in-core label for the whole disk. 
Callers only need to initialize d_secperunit now, but should
initialize d_type (to reduce the IDE/SCSI confusion), d_typename
(put the disk model in it) and geometry info (if it isn't completely
ficticious).  Callers will soon need to initialize d_secsize.

all for the !DEVFS case, but this was harmless on i386's).

1e550e3809 Backed out rev.1.43 (removed nonsense SLICE ifdef). SLICE is 
normally only defined in opt_devfs.h, so testing it before including
anything is normally a no-op.  Undef'ing DEVFS before including
opt_devfs.h is similarly useless.  OTOH, DEVFS support for sliced
but not SLICEd (despite defined(SLICE)) devices is either harmless
(if there are no such devices, then nothing in this file is used)
or necessary (otherwise).  It even seems to work for sliced cd
devices.

f2bd332e7c Stop physical DMA for the non-auto case in isa_dmadone(). This fixes a 
small part of a bug suite beginning in the SLICE probes but mostly in the
floppy driver.  This is a quick fix: the auto case shouldn't be special;
DMA should also be stopped in isa_dma_release(); isa_dmastop() probably
shouldn't exist; common DMA registers should not be accessed without
locking.

e5d7d24361 Fixed error handling after a seek error that can't happen. When the 
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case.  This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested.  The fix is simply to arrange to reset the state
machine.

Corruption of the buffer queue seems to only have been a problem in the
floppy driver.  Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order.  Dequeueing breaks it anyway.
