Subject: [PATCH v3 08/29] x86/cacheinfo: Constify _cpuid4_info_regs instances
Date: Wed, 19 Mar 2025 13:21:16 +0100 [thread overview]
Message-ID: <20250319122137.4004-9-darwi@linutronix.de> (raw)
In-Reply-To: <20250319122137.4004-1-darwi@linutronix.de>
_cpuid4_info_regs instances are passed through a large number of
functions at cacheinfo.c. For clarity, constify the instance parameters
where _cpuid4_info_regs is only read from.
