Subject: [rfc -tip] x86, apic: Get rid of some IPI wrappers
They just hide the sameness of methods.
Signed-off-by: Cyrill Gorcunov <gorcunov@...nvz.org>
---
I may be missing something but frankly I don't see the reason for
hiding sameness here, the reverse -- if you're going to change something
then instead of looking into direct method implementation you are to
tear through wrapping calls. Of course if implementation is differ from
'default_' one (as in x2apic, uv) it deserves own method.
No?
