Let's support __HAVE_ARCH_PTE_SWP_EXCLUSIVE by stealing one bit from the offset. This reduces the maximum swap space per file: on 32bit to 16 GiB (was 32 GiB).Seems fine to me, I doubt anyone wants a huge pile of swap on rv32.
Patch is already upstream, so we can't add tags unfortunately. Thanks for the review! -- Thanks, David / dhildenb
