Applied to my -fixes tree.
Btw while I'm okay to merge this as a workaround, I'd really like to know if someone cares enough to fix it.
Because there is no reason WC mappings should be broken on 32-bit, and its quite likely they are broken on 64-bit too just more subtly.
It would definitely be nice to get to the bottom of this, but I'm not sure where to dig next. Given that basically the same 64-bit kernel seems to fail when built on a 32-bit host but works fine when built on a 64-bit host, I suspect it might be something from the host toolchain / build environment leaking into the resulting binaries somehow.
