Subject: [PATCH 2/5] riscv: sbi: Use IPI_MAX for SBI IPI muxing
Date: Sun, 16 Aug 2026 07:00:46 +0000	[thread overview]
Message-ID: <20260816070049.2097442-3-guoren@kernel.org> (raw)
In-Reply-To: <20260816070049.2097442-1-guoren@kernel.org>

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

Now that IPI_MAX is visible from <asm/smp.h>, replace the hard-coded
BITS_PER_BYTE with the proper symbolic constant in the SBI IPI
extension driver.

No functional change; IPI_MAX is still 8.
