From 9a7a0773d7d2fd1e4c581f42ad75de7872a174dc Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 2 Aug 2019 20:56:45 +1000 Subject: [PATCH] powerpc/64s/exception: Fix performance monitor virt handler The perf virt handler uses EXCEPTION_PROLOG_2_REAL rather than _VIRT. In practice this is okay because the _REAL variant is usable by virt mode interrupts, but should be fixed (and is a performance win).
