Subject: [PATCH 1/7] x86: Move ARCH_HAS_CPU_RELAX to arch
Date: Mon, 20 Nov 2023 16:01:32 +0200	[thread overview]
Message-ID: <1700488898-12431-2-git-send-email-mihai.carabas@oracle.com> (raw)
In-Reply-To: <1700488898-12431-1-git-send-email-mihai.carabas@oracle.com>

From: Joao Martins <joao.m.martins@oracle.com>

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.
