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.

option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.
options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory

- Make generic console routines not relying on running on master cpu.
- Add routine to start console transmitter (after IPI).
- Use real IPIs instead of the "console doorbell".
- Add routines cpu_send_ipi()/cpu_handle_ipi().
