Subject: parisc: Pass endianness info to sparse
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3744d988c05a27f40408003352841aefadba1324;p=openwrt%2Fstaging%2Fblogic.git

parisc: Pass endianness info to sparse

parisc is big-endian only but sparse assumes the same endianness as the
building machine.
This is problematic for code which expect __BYTE_ORDER__ being correctly
predefined by the compiler which sparse can then pre-process differently
from what gcc would.

Fix this by letting sparse know about the architecture endianness.
