parisc: Define CONFIG_CPU_BIG_ENDIAN
While working on enabling queued rwlock on SPARC, found this following code in include/asm-generic/qrwlock.h which uses CONFIG_CPU_BIG_ENDIAN to clear a byte. static inline u8 *__qrwlock_write_byte(struct qrwlock *lock) { return (u8 *)lock + 3 * IS_BUILTIN(CONFIG_CPU_BIG_ENDIAN); } Problem is many of the fixed big endian architectures don't define CPU_BIG_ENDIAN and clears the wrong byte. Define CPU_BIG_ENDIAN for parisc architecture to fix it. Signed-off-by: Babu Moger <babu.moger@oracle.com> Signed-off-by: Helge Deller <deller@gmx.de>
