From 0edaee42eb8c0f3b767ec3c51bee4a3855aa2555 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Mon, 9 Nov 2020 17:08:36 +0530 Subject: [PATCH] arm64/smp: Drop the macro S(x,s) 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.
