glibc headers define both __LITTLE_ENDIAN and __BIG_ENDIAN
|
|
which was tripping the check in linux/byteorder.h. Let's
|
|
just stay out of userspace's way and use __KERN_{endian}
|
|
|
|
The old implementation got away with it as it kept the two
|
|
implementations in different headers and conditionally included
|
|
the right one. The combined header does checks within each
|
|
function body and depends on only one being defined.
|
|
|
|
Converted the arches in mainline that have already moved to the
|
|
new header, as the other arches merge the will need simlar
|
|
fixups.
