Subject: [PATCH 4/5] irqchip/aclint-sswi: Use IPI_MAX for IPI muxing
Date: Sun, 16 Aug 2026 07:00:48 +0000	[thread overview]
Message-ID: <20260816070049.2097442-5-guoren@kernel.org> (raw)
In-Reply-To: <20260816070049.2097442-1-guoren@kernel.org>

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

Replace the hard-coded BITS_PER_BYTE with IPI_MAX now that the constant
is exported from riscv asm/smp.h.
