ARM: 9033/1: arm/smp: Drop the macro S(x,s) (27bde183) · Commits · 戴 / test

Mapping between IPI type index and its string is direct without requiring an additional offset. Hence the existing macro S(x, s) is now redundant and can just be dropped. This also makes the code clean and simple. Cc: Marc Zyngier <maz@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org Signed-off-by:
