Bruce Evans 9463bb149a Updated lkm examples to work with prototype-related changes to the
MOD_MISC() and DISPATCH() macros.

Renamed new_syscall module as new_syscall_mod.  It seems to be standard
to have module names ending with _mod, and this may be forced when
MOD_SYSCALL() and MOD_VFS() are updated to match MOD_MISC().

Cleaned up lkm examples a little.
