From 4ab2537c4204b976e4ca350bbdc193b4649cad28 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Thu, 8 Dec 2016 09:12:13 +0530 Subject: [PATCH] powerpc/mm: Fixup wrong LPCR_VRMASD value In commit a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated LPCR_VRMASD wrongly as below. -#define LPCR_VRMASD (0x1ful << (63-16)) +#define LPCR_VRMASD_SH 47 +#define LPCR_VRMASD (ASM_CONST(1) << LPCR_VRMASD_SH) We initialize the VRMA bits in LPCR to 0x00 in kvm. Hence using a different mask value as above while updating lpcr should not have any impact. This patch updates it to the correct value.
