That's why the bitmaps are defined as little endian u64 aligned, even on
big endian 32-bit systems. Little endian bitmaps are wordsize agnostic,
and u64 alignment ensures we can

Yes, I'm just using in kernel space: qemu has its own endian related helpers.
So if you allow us to place this macro in asm-generic/bitops/* it will help us.
No problem at all then. Thanks for the explanation.

Thanks you both. I will add your Acked-by

Although we can use *_le_bit() helpers to treat bitmaps le arranged,
having le bit offset calculation as a seperate macro gives us more freedom.
For example, KVM has le arranged dirty bitmaps for VGA, live-migration
and they are used in user space too. To avoid bitmap copies between kernel
and
