commit 896842284c6ccba25ec9d78b7b6e62cdd507c083 upstream. fadvise64_64() has two 64-bit arguments at the wrong alignment for hexagon, which turns them into a 7-argument syscall that is not supported by Linux. The downstream musl port for hexagon actually asks for a 6-argument version the same way we do it on arm, csky, powerpc, so make the kernel do it the same way to avoid having to change both.
