Subject: [PATCH v1 18/26] arm64: Extract cache definitions
Date: Fri, 29 May 2026 17:55:51 +0200	[thread overview]
Message-ID: <20260529155601.2927240-19-seiden@linux.ibm.com> (raw)
In-Reply-To: <20260529155601.2927240-1-seiden@linux.ibm.com>

Move CPU type definitions from arch/arm64/include/asm/cache.h.h to
include/arch/arm64/asm/cache-defs.h to prepare sharing with other
architectures. No functional changes.
