if you care about the last cycle, don't specify -Os but -O2.
simple as that... you get what you tell the compiler you want.
Certain distros are shipping kernels compiled with -Os. And it's more
than just a couple of cycles.
so those distros pick space over some cycles. Who are you to then
override that choice ? ;-)
seriously, why are we even talking about overriding a choice the user
(or distro vendor as user) made here?
