H A Dmi1.2499 Sat Sep 06 02:53:21 GMT 2025 riastradh paravirt_membar_sync(9): New memory barrier.

For use in paravirtualized drivers which require store-before-load
ordering -- irrespective of whether the kernel is built for a single
processor, or whether the (virtual) machine is booted with a single
processor.

This is even required on architectures that don't even have a
store-before-load ordering barrier, like m68k; adding, e.g., a virtio
bus is _as if_ the architecture has been extended with relaxed memory
ordering when talking with that new bus. Such architectures need
some way to request the hypervisor enforce that ordering -- on m68k,
that's done by issuing a CASL instruction, which qemu maps to an
atomic r/m/w with sequential consistency ordering in the host.
