/* 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. */
