Based on commit 385864280597 ("mips: csrc-r4k: Mark R4K timer as unstable
if CPU freq changes") which added some of this stuff shouldn't the flag be
set instead?
At first glance the situation seems analogous to that of the x86 TSC:
just as the TSC the R4k timer is a CPU onchip free-running counter driven
by the CPU clock (typically at half the rate).
