From 4762bbc1a3a1f22095278b74dd1b8cee04858641 Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Mon, 24 May 2010 14:33:31 -0700 Subject: [PATCH] crc32: use __BYTE_ORDER macro for endian detection. Since crc32.c contains a nifty test program that can be executed in user space, make sure endian detection works reliably in user space too.
