Ok, looks like you screwed up the types according to the build server.
Making the return type "unsigned long" is slightly excessive. If you
need an unsigned long to describe the log2 of a number in the kernel,
you're playing with numbers that are *way* too big.
The old code used "ilog2()", which returns an int.
Which is plenty big enough of a type.
