[PATCH] i386: PARAVIRT: use paravirt_nop to consistently mark no-op operations

Browse source

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.

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
