[PATCH v3 1/7] x86: Move ARCH_HAS_CPU_RELAX to arch

From: Mihai Carabas
Date: Mon Jan 29 2024 - 06:57:04 EST


From: Joao Martins <joao.m.martins@xxxxxxxxxx>

ARM64 is going to use it for haltpoll support (for poll-state)
so move the definition to be arch-agnostic and allow architectures
to override it.
