Add a _paravirt_nop function for use as a stub for no-op operations, and paravirt_nop #defined void * version to make using it easier (since all its uses are as a void *). This is useful to allow the patcher to automatically identify noop operations so it can simply nop out the callsite.
Acked-by: Ingo Molnar <redacted>
+void _paravirt_nop(void); +#define paravirt_nop ((void *)_paravirt_nop)
but only as a cleanup of the current open-coded (void *) casts. My problem with this is that it loses the types. Not that there is much to check for, but still, this adds some assumptions about how function calls look like. Ingo
