9c96ae361d Notify pmap when a page is freed on the alpha to allow it to clean up

03ddb15c2b Fix a stupid bug in the new pmap_remove(). 
Arrange for soft modified/referenced flags to be cleared when a page is freed.

3b18043bd8 Don't pass the label to diskerr(), since the label is being constructed 
and may be invalid.  In particular, d_secpercyl may be 0, and diskerr()
divides by it.

f424d5f084 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.

c77c9fb18b Don't return an error if the magic number is not present. 
Failing to probe is not an error, just a negative result.

8414aaec0d Add a call to a platform-specific irq remapping function for alpha platforms 
which don't record the correct irqs in PCI config space.

02ecd6d029 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.

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.
