+Subject: [PATCH] UAPI: include <asm/byteorder.h> in linux/raid/md_p.h
+Forwarded: http://comments.gmane.org/gmane.linux.kernel/1586604
+
+linux/raid/md_p.h is using conditionals depending on endianess and fails
+with an error if neither of __BIG_ENDIAN, __LITTLE_ENDIAN or
+__BYTE_ORDER are defined, but it doesn't include any header which can
+define these constants. This make this header unusable alone.
+
+This patch adds a #include <asm/byteorder.h> at the beginning of this
+header to make it usable alone. This is needed to compile klibc on MIPS.
