From 19e68b2aec3c0a2bd770d3c358a296a1849f308a Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Thu, 22 Mar 2018 22:03:18 +0100 Subject: [PATCH] powerpc/mm/radix: Fix always false comparison against MMU_NO_CONTEXT In commit 9690c1574268 ("powerpc/mm/radix: Fix always false comparison against MMU_NO_CONTEXT") an issue was discovered where `mm->context.id` was being truncated to an `unsigned int`, while the PID is actually an `unsigned long`. Update the earlier patch by fixing one remaining occurrence.
