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.

Hi Andy et al,

Any feedback on the fix? Does it work on 64 LE for you?

Thanks!

Thanks!
