Palmer Dabbelt 77c14a5e4d RISC-V: Upgrade smp_mb__after_spinlock() to iorw,iorw ... [ Upstream commit 38b7c2a3ff ] While digging through the recent mmiowb preemption issue it came up that we aren't actually preventing IO from crossing a scheduling boundary. While it's a bit ugly to overload smp_mb__after_spinlock() with this behavior, it's what PowerPC is doing so there's some precedent.
