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.
