disksubr.c: kill register, use explicit types (egcs).
kgdb_machdep.c: There is no pmap_pte in pmap.new.c, use kvtopte.
locore.s: PTmap, PTD and PTDpde are not used with pmap.new.c.
machdep.c: remove unused reference to panicstr (egcs).
Some pmap.new.c changes.
vm_machdep.c: Change i386_btop to ns532_btop in pmap.new.c code.
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)
locore.s:
- cpu_switch "returns" to proc_trampoline after cpu_fork. cpu_switch is
called with an argument, remove it from the stack when not compiled
with -DMRTD.
- use KENTRY instead of ENTRY for all functions called from C.
- when calling C code, don't clean up the stack when compiled with -DMRTD.
- need to split fusubail into fubail and subail, because fu and su
take different number of arguments.
machdep.c:
- set sf_p when dumping
- new function do_softclock (that just calls softclock) because softclock
doesn't take an argument.
mainbus.c:
- establish softclock interrupt to call do_softclock
trap.c:
- trap() and syscall() allways use std C calling conventions.
- need to split fusubail into fubail and subail, because fu and su
take different number of arguments.
- make child_return take only one argument like the other functions
"called" via cpu_set_kpc.
vm_machdep.c:
- set sf_p in cpu_fork.
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
