Now that sbus_bus_mmap was converted to do the proper address

translation, get rid of sbus_bus_addr. Since sbus_bus_addr is used by

sparc64 that uses a different calling protocol, so stub our
sbus_bus_addr to just return BUS_ADDR.

Also, the fork system call never uses the SYSCALL_G2RFLAG shortcut, so drop
the code handling that.

microSPARC-IIep is a sun4m but with an integrated PCI controller.
...
In a lot of places (like pmap &c) we want it to be treated as SUN4M.
But since various low-level things are done very differently from
normal sparcs (and since for now it requires a relocated kernel
anyway), the MSIIEP kernels are not supposed to support any other
system. So when MSIIEP is defined - insist on SUN4M defined and SUN4
and SUN4C not defined.

correct mcount name).

Change defaults for kernel compiles. Default all to USETOOLS?=no and have

the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed

Adjust each ports template to set the default no setting and also pull in

Update pmap_update to now take the updated pmap as an argument.
...
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

options SYSVSHM # System V shared memory

correct it.
