From 04b9c96eae72d862726f2f4bfcec2078240c33c5 Mon Sep 17 00:00:00 2001 From: Balbir Singh Date: Fri, 15 Dec 2017 19:14:54 +1100 Subject: [PATCH] powerpc/crash: Remove the test for cpu_online in the IPI callback Our check was extra cautious, we've audited crash_send_ipi and it sends an IPI only to online CPU's. Removal of this check should have not functional impact on crash kdump.
