This patch is interesting because it uses calc_mult_shift() and the current
localtimer driver for TWD (arch/arm/kernel/smp_twd.c) still uses hardcoded
mult+shift.
So this patch in combination with TGLX add-on in the CPUfreq path would
eliminate the need of using the prescaler at all, which is a more appealing
solution to me for one, since it results in less code.
Colin, do you think it will work? Or was there some specific reason to use
a dynamic prescaler instead of doing things like this?
Yours,
Linus Walleij
