Patch Set 1:

Please add it under commonlib and use qsort.

I agree with the commonlib-part, will move it to this location.
Regarding the algorithm itself I would like tostick with bubblesort for the following reasons:
-it is simple
-it might turn out that there is a need for a stable sorting algo. Qsort is not stable while bubble sort is
-The amount of data to sort in this given case (acpi MADT) is short (up to MAX_CPUS). There is no benefit in qsort vs. bubblesort on this data set
-bubblesort does not need to stay the only algo in sort.c. It is more meant as a general location for different sorting algos, which can be added on demand there.
