d9b2f81e27 move pdhist initialisation to the same place as maphist. also, declare 
the history buffers are "struct uvm_history_ent" to ensure proper
alignment (eg, alpha).  this fixes a boottime panic when the pdhist was
used before it had been initialised.

1305ecbe62 Allow callers of uvm_km_suballoc() to specify where the base of the 
submap _must_ begin, by adding a "fixed" boolean argument.

22c20779d0 Rewrite the match/attch routines to use the P4 register 
(when it exists).  Also get the size right; other fixes.

0378cb2ff6 Define the CG4B_OFF_* values to be relative to the location of 
the P4 register so the probe routine finds the P4 at off=0.

99fd045ec0 Add fb_eeprom_setsize() for setting the FB size based on the EEPROM 
value (to be used only if unit=0).  Add P4 helper functions:
fb_pfour_id, fb_pfour_setsize, fb_pfour_{get,set}_video

5193e1e30e Factor *peek out of bus_subr.c and move it to autoconf.c 
(to reduce duplication).  Add bus_tmapin and bus_tmapout
for use in probe functions (gets a temporary mapping).
Add bus_mapout() to undo bus_mapin() if needed.

cc06ca6693 * Add the "VIPER 150/21531" to quirk list (ST_Q_SENSE_HELP).

8e8eed4ba7 Create RX DMA maps with ALLOCNOW. These maps are essentially always 
loaded, and recovering from a resource shortage error is much harder
in the receive case.

c2f8ffc062 reserve some pages for the kernel, and some more especially

5942e0ff3d initial implementation of OFW ISA bus code and attachments for a few 
devices.  Still a bit rough, but works well enough.  Requires a bunch of
machine-dependent glue (since this is, in effect, a MI bus bridge).
