Subject: crc32: use __BYTE_ORDER macro for endian detection.
X-Git-Tag: v2.6.35-rc1~305
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=4762bbc1a3a1f22095278b74dd1b8cee04858641

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.
