5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven geert@linux-m68k.org
[ Upstream commit 6d5674090543b89aac0c177d67e5fb32ddc53804 ]
The function signatures of the m68k-optimized implementations of the find_{first,next}_{,zero_}bit() helpers do not match the generic variants.
Fix this by changing all non-pointer inputs and outputs to "unsigned long", and updating a few local variables.
