Does the following work for you? For simplicity, I copied__is_constexpr from
include/linux/minmax.h (which isn't available in tools/). A proper patch
would reuse __is_constexpr (possibly refactoring it to a separate
header since bits.h including minmax.h for that only seems smelly)

I think we need to have it in something like compiler.h (top level). Under
'top level' I meant something with the function as of compiler.h but with
Linuxisms rather than compiler attributes or so.

Separate header for the (single) macro is too much...

and fix
bits.h in the kernel header as well, to keep the files in sync.

Right.
