Update of /a/cvsroot/src/sys/arch/pmax/pmax
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv23071

Modified Files:
	trap.c 
Log Message:
Include <machine/locore.h>, to force all MIPS cpu-model specific
locore calls to go via a locore-entry jumptable.

Declare  r2000- and r4000-specific exception-handler functions, to which
trap() and interrupt() dispatch exceptions. Initialize r2000- and r4000-
specific exception-handler vectors, when CPU_R4000 and CPU_R2000 are
defined.

Update the stack-traceback code (partially) to understand and print
the new low-level exception-handler code, via which machine exception-vectors
send exceptions to call trap() or interrupt(). This needs  more work.

Modified Files:
	pmap.c 
Log Message:
Include <machine/locore.h>, to force all MIPS cpu-model specific
locore calls to go via a locore-entry jumptable.

Use mips_btop(), mips_round_page, mips_trunc_seg() instead
of pmax_btop(), pmax_round_page, pmax_trunc_seg().

Add Per's software-readonly-bit mechanism, since the r2000 and r4000
hardware TLB entries are  very different, and the r4k has no space for
software bits in TLB entries.  That is, this pmap code still won't work
on r4000 machines. Some other solution, like another jump table for
clients of the  pmap code, is necessary.
