Subject: [PATCH 1/7] cpuidle-haltpoll: Make boot_option_idle_override check X86 specific
Date: Wed, 9 Aug 2023 14:39:35 +0300 [thread overview]
Message-ID: <1691581193-8416-2-git-send-email-mihai.carabas@oracle.com> (raw)
In-Reply-To: <1691581193-8416-1-git-send-email-mihai.carabas@oracle.com>
From: Joao Martins <joao.m.martins@oracle.com>
In the pursuit of letting it build on ARM let's not include what is x86
specific.
