[PATCH 1/8] linux/types.h: enable endian checks for all sparse builds

From: Michael S. Tsirkin
Date: Thu Dec 15 2016 - 00:17:26 EST


By now, linux is mostly endian-clean. Enabling endian-ness
checks for everyone produces about 200 new sparse warnings for me -
less than 10% over the 2000 sparse warnings already there.

Not a big deal, OTOH enabling this helps people notice
they are introducing new bugs.

So let's just drop __CHECK_ENDIAN__. Follow-up patches
can drop distinction between __bitwise and __bitwise__.
