commit 896842284c 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.
