Boot-tested under QEMU for Rust x86_64, arm64 and riscv64; built-tested
for loongarch64:
Tested-by: Miguel Ojeda <ojeda@kernel.org>
For UML, I am seeing:

In file included from ./include/linux/unwind_user.h:6:

We probably need at least:
aa7387e79a5c ("unwind_user/x86: Fix arch=um build")
Or perhaps the split of the guards added later.
