Yes, but it still changes them. It might have a larger impact
on code size for example.
Only if CONFIG_PARAVIRT is defined.
Which eventually distribution kernels will do.
And even then, all the performance
sensitive stuff uses mmio, no?
Not worried about performance, but just impact on code size etc.
Ah. But that's mostly modules, so real in-core changes should be very
small (say 10 bytes per call site X 10 callsites per driver X 10
drivers... even if off by an order of magnitude it's still tiny)
