Subject: [PATCH 1/5] riscv: smp: Move enum ipi_message_type to asm/smp.h
Date: Sun, 16 Aug 2026 07:00:45 +0000	[thread overview]
Message-ID: <20260816070049.2097442-2-guoren@kernel.org> (raw)
In-Reply-To: <20260816070049.2097442-1-guoren@kernel.org>

From: "GUO Ren (XuanTie)" <guoren@kernel.org>

The IPI message type enumeration (and therefore IPI_MAX) is currently
private to arch/riscv/kernel/smp.c.  Several IPI providers need to know
the exact number of IPIs that the architecture requires, so move the
enum into the public header.

This is a pure code movement with no functional change.
