We are spending between 40 and 160 cycles with a mean of 65 cycles
in the TLB handling routines (measured with mftbl) so make it more
simple althought it adds one instruction

Why is this a separate patch from 1/25?

Same comments as on that patch.
Just because here there is no real need behind the simplification of the

Should I merge them together anyway ?
