Overall the idea seems right though - we should have something like
#ifndef __BACKPORT_BITOPS_H
#define __BACKPORT_BITOPS_H
#include_next <linux/bitops.h>
#ifndef for_each_set_bit
#define for_each_set_bit(...) \
...
#endif
#if kernel_version < 2.6.38
static inline __s32 sign_extend32(...) { ... }
#endif
etc.
#endif /* __BACKPORT_BITOPS_H */
I think.
