101e6d7c92 There is a comment in vm_param.h which doesn't belong to the 
code still left in there.  The macros it describes disapeared some-
time since 4.4BSD lite.

8f5a35b01d 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.

79b1340c5b Moved allocation of the slices struct to the right place. Initialize 
everything in it (the devsw pointers were not initialized early or at
all for the !DEVFS case, but this was harmless on i386's).

6bdff03bd1 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.

d4548c1c49 A slap on the wrist to Dag-Erling, who plainly did not test this before 
committing it.  There was a large syntax error at line 404 which could
not possibly have allowed compilation. :)

39d6cd0751 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.

7466f92c1a 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.
