Re: proposition for fixing Y292B bug

[David Polakovic <email@dpolakovic.space>]

Thanks for reply.

My proposed solution was to create this BigInt datatype, which
stores the value in array. The functions for division, multiplication,
addition, subtraction and comparison could be stored in separate
".h" library for manipulation with BigInt datatype. The paper speaks
more in detail.

And yes, this truly is an userspace solution, but for kernel space
implementation I have zero to none experience. Therefore I wrote
here.
