[PATCH for 5.0 v1 1/2] riscv: Don't use stage-2 PTE lookup protection fl


From: Alistair Francis
Subject: [PATCH for 5.0 v1 1/2] riscv: Don't use stage-2 PTE lookup protection flags
Date: Thu, 26 Mar 2020 15:44:07 -0700

When doing the fist of a two stage lookup (Hypervisor extensions) don't
set the current protection flags from the second stage lookup of the
base address PTE.
