Subject: [PATCH v2 02/15] system/cpus: Constify various CPUState arguments
Date: Thu, 20 Aug 2026 22:13:42 +0200	[thread overview]
Message-ID: <20260820201356.29775-3-philmd@oss.qualcomm.com> (raw)
In-Reply-To: <20260820201356.29775-1-philmd@oss.qualcomm.com>

Mark the CPUState structure const when it is only accessed read-only.
