This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

and call it directly from tcp_slowtimo() (via a table) rather
than going through tcp_userreq().
This will allow us to call TCP timers directly from callouts,
in a future revision.
(i.e. processes started from shell scripts). Fixes problem where kill -STOP'ing
a subprocess of a shell script would cause the shell to proceed to the next
command.
this file; while I'm here, rework the GIO arbitrator parameter setup to
match more closely what is done by lunix on the same hardware... Finally,
on a tip from Wilbern Cobb, preserve the graphics-related bits of the
GIO arbitrator parameter register from the PROM-initialized settings so
ARCS console on the graphics display works (tested on both my Indy with
Newport and my Indigo2 with XL gfx).
Instead of incrementing t_idle and t_rtt in tcp_slowtimo(), we now
take a timstamp (via tcp_now) and use subtraction to compute the
delta when we actually need it (using unsigned arithmetic so that
tcp_now wrapping is handled correctly).
Based on similar changes in FreeBSD.
be spread over several devices, and the phcb is usually the main one.
Add agp_machdep.c file which implements MD agp functions (currently
just agp_flush_cache).
function on all (probed) PCI buses:
int pci_find_device(struct pci_attach_args *pa,
int (*match)(struct pci_attach_args *));
The pci_attach_args structure pointed to by pa is filled in if the
device is found, and 1 is returned. Otherwise 0 is returned.
This function is, unfortunately, needed by the i810 agp code. It's
also of use for LKMs.
Also frob pci_probe_bus to take 2 extra args when used by pci_find_device.
