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
Fixes: a4b349540a26af ("powerpc/mm: Cleanup LPCR defines") we updated
