Boot-tested under QEMU for Rust x86_64, arm64 and riscv64; built-tested
for loongarch64:

Tested-by: Miguel Ojeda <ojeda@kernel.org>

For UML (x86_64) I am seeing:

    1 error generated.

Caused by commit 95721c9fb3a1 ("srcu: Use irq_work to start GP in tiny
SRCU"). The header seems to simply not be there, i.e. either the
`#include` is changed or commit c809f081fe40 ("irqwork: Move data struct
to a types header") is backported.
