We add 'BUILD_BUG_ON((__msk & __en) != 0);' to prevent coding error during
development. The __msk and __en in the expression are constant and expected
no intersection of these two bit masks. Since we have verified this code,
I think I can send a patch to remove the BUILD_BUG_ON() from this macro.
Thank you

I'm dropping the patchset, please submit a new version including your
fix.
