Subject: [PATCH v2 3/6] clocksource: clint: Use IPI_MAX for IPI muxing
Date: Fri, 11 Sep 2026 03:27:11 +0000	[thread overview]
Message-ID: <20260911-ipi_max-v2-3-a77826ff189e@kernel.org> (raw)
In-Reply-To: <20260911-ipi_max-v2-0-a77826ff189e@kernel.org>

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