* dcparam() with normal tty t_param interface, which calls
* cold_dcparam() called with explicit dc7085 register address
and flags, which does the work and is also callable when cold,
to set up console (or kgdb) line parameters.
* use mips_round_page,mips_trunc_seg() instead of
pica_round_page(),pica_trunc_page().
* discard (unused) return value from TLBUpdate(), and delete
(unused) temporary variable used to hold it.
* Move mips-I pte (TLBlo) definitions from pmax/include/pte.h
to mips/include/mips1_pte.h
* Move mips-III pte (TLBlo) definitions from pica/include/pte.h
to mips/include/mips3_pte.h
* Add new mips/include/pte.h, which includes exactly one of
mips1_pte.h or mips3_pte.h (which still have namespace collisions),
depending on "options MIPS1" or "options MIPS3". (hack).
Move soft kvtopte(), ptetovk() definitions to mips/include/pte.h
* Add macro PTE_TO_PADDR() to hide the different hardware TLB formats
when mapping from pte to physical address.
* Add macro PTE_READONLY() to hide lack of SW read-only bit in mips-III
tlb. (mips1 pmap uses a sw bit in the PTE, mips3 looks up RO bit in
the kernel pmap.)
* Use macros (not direct TLB frobbing) in mips/trap.c, to make it
mips-1/mips-III indepenndet.
* Change {pmax,pica}/include/pte.h to just do #include <mips/pte.h>.
jump-table) locore entrypoints, so the stack traceback code can use
the end marker to handle entry points specially when doing tracebacks,
even if it doesn't know about them explicitly.
* fold in netBSD style changes:
``if (foo = bar)'' -> ``if ((foo = bar) != 0)''
* add mips1 vector as well as mips3 vector
* change vector names to make mips1 and mips3 locore entrpoints distinct
* add pmax additions (e.g., old fixes to ktrace code, kernel-TLB_miss
instrumentation)
* update stack traceback code to a newer version of the pmax code.
add catch-all case, with distinct mips1 and mips3 ranges for locore
entry points, cases to catch othewise-unknown locore entrypoints and
vector code (which have special entry sequences and require special
support to trace through). The relevant mips1 and mips3 functions are
of course now distinct.
NetBSD-current changes:
* change include paths to be relative to the kernel-source tree
(e.g., `/sys') instead of arch/pmax/conf.
* add explicit options for exec packages (EXEC_ELF32, EXEC_ECOFF
for COMPAT_ULTRIX)
* comment out references to still-unsuppoted MI scsi.
