-/* If true, system calls save and restore all registers (except result
- registers, of course). If false, then `call clobbered' registers
- will not be preserved, on the theory that system calls are basically
- function calls anyway, and the caller should be able to deal with it.
- This is a security risk, of course, as `internal' values may leak out
- after a system call, but that certainly doesn't matter very much for
- a processor with no MMU protection! For a protected-mode kernel, it
- would be faster to just zero those registers before returning. */

/* These are special variables using by the kernel trap/interrupt code
to save registers in, at a time when there are no spare registers we
can use to do so, and we can't depend on the value of the stack
