Subject: linux/types.h: enable endian checks for all sparse builds
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=05de97003c773e7881e4df3f767b81a6508107f2;p=linux-beck.git

linux/types.h: enable endian checks for all sparse builds

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__.
