Sorry for late reply.

Please use the function which calculates the optimizes mult/shift
values for you depending on the clock frequency.

clockevents_calc_mult_shift() is your friend.

Please convert your irq_chips to the new function pointers:

       .mask -> .irq_mask
       ...

The new functions replace the "unsigned int irq" argument with
"struct irq_data *d".

So conversion for your chips is simply

s/unsigned int irq/struct irq_data *d/

and 

s/irq/d->irq/ in the implementation.

Then your arch should select: GENERIC_HARDIRQS_NO_DEPRECATED

Otherwise I'm happy with your irq and time related patches.

Thanks,
