No. I exposed my reasoning, asked you back, but got no answer.
I'll do it again:
This operations are just manipulating bits, and are doing no
privileged operations at all. Nothing that can be paravirtualized, in
It's talking to a Hypervisor. That is privileged enough.
Please do that change. If you add so many more ifdefs it's your
duty to keep the overall number low.
Again, this is the code of such function:
static inline int raw_irqs_disabled_flags(unsigned long flags)
{
return !(flags & X86_EFLAGS_IF);
}
so all it is doing is getting a parameter (flags), and bitmasking it. It
is not talking to any hypervisor. I can't see your point. Unless you are
arguing that it _should_ be talking to a hypervisor. Is that your point?
If it is the case, please tell me why. My current understanding is that
we want to keep few changes from the normal kernel. So there is not too
much reason for it.
