3d2cea267e Commit change missed during Decsystem 5100 chagnes: 
prototype declearation for method to override wbflush() callback
vector with model-specific code. Used on DEC r2000a machines with
writebuffers which indicate writebuffer drain via cp0 usability bit.

7782adb98e Use r12 as a temporary register in setrunqueue() and remrunqueue() as it 
does not need to be preserved across function calls. This means the use
of r4 can be eliminated thus saving a stack push and pop for r4.

optimial checking.

d47bc69126 Rework pmax kernel config: 
* ibus (virtual bus for baseboard direct-attach deviecs)
 * 5100 support, using ibus
 * rename "clock" to mcclock for future support of Qbus machiens
 * use sys/dev/dec mcclock_pad32 machinery for pmax mcclock
 * reworked TC config code.

216daa4e5e Configure mips_mclock if "clock|mccclock". 
All(?) ARC boxes use mcclock, but QBus decstations use the same
time-of-year clock architecturally mandated for VAXes.

9caaf18836 Rework pmax turbochannel config, as suggested by Jason Thorpe. 
Also make TC framebuffer-console search table-driven.

Does not yet include "tcasic" layer; there's no such hardware on DECstations
and nothing for a tcasic layer to do.

c84f4e94d9 Copy alpha/tc/mcclock_ioasic.c (duplicated in pmax/tc/mcclock_ioasic.c) 
into sys/dev/dec and split into a clockfns layer and a "middle" layer
for other DEC systems which use mcclocks with each onchip byte
register padded out to a 32-bit word.

Clone alpha/alpha/mcclock (also duplicated in pmax port) into
sys/dev/dec, and ifdef for default clockrates on pmax and alpha.

Use new machinery on pmax for ibus,ioasic attached mcclocks.

rpc_sa110_cc_setup().
