Subject: [PATCH 1/3] vmlinux.lds.h: add _handle_arch_irq RUNTIME_CONST section
Date: Fri, 20 Feb 2026 17:09:20 +0800 [thread overview]
Message-ID: <20260220090922.1506-2-jszhang@kernel.org> (raw)
In-Reply-To: <20260220090922.1506-1-jszhang@kernel.org>
We will use the runtime constant to optimize the handle_arch_irq
accessing. This is preparation patch.
