 Hi,
 
 thanks, from what I can see your patch does "effectively the same",
 just with slightly other rounding/bucket distribution if repeated
 dividing by 2 requires rounding before getting to a number in [1, 8]
 (i.e., the right condition is not N*[1..8], but 2^N*[1..8]).
 
 For a "bad" number of CPUs it now behaves better for me.  I didn't
 test all numbers, but for the few that I tried I successfully booted.
 
 So:  looks good, thanks!
