Subject: [PATCH v2 2/4] cpuidle: haltpoll: Remove single state handling
Date: Tue, 17 Feb 2026 00:20:03 +0530 [thread overview]
Message-ID: <20260216185005.1131593-3-aboorvad@linux.ibm.com> (raw)
In-Reply-To: <20260216185005.1131593-1-aboorvad@linux.ibm.com>
cpuidle systems where the governor has no choice because there's only
a single idle state are now handled by cpuidle core and bypass the
governor, so remove the related handling.
