Subject: [PATCH] include/bitmap.h: add new functions to documentation
I found these functions only by chance although I was looking exactly
for something like them. So, add them to the list of functions to make
them more visible.
Fixes: e837dfde15a4 ("bitmap: genericize percpu bitmap region iterators")
