Commit 2d6261583be0 ("lib: rework bitmap_parse()") does not take into account order of halfwords on 64-bit big endian architectures.

Thanks for report and the patch!

Did it work before? Can we have a test case for that that we will see the failure?

The test exists and enabled with CONFIG_TEST_BITMAP. It does not appear ever passed before on 64 BE. It does not fail on 64 LE for me either.

Thanks!
