The function returns address of physical memory mapped at the supplied
kernel virtual address.
Sure, this is more accurate.
I suggest tweaking this further just to be very explicit about the type

The
.Fn pmap_kextract
function returns the physical address of memory mapped at the
kernel virtual address
.Va va .
