Subject: [PATCH 8/9] riscv: module: Create module allocations without exec permissions

From: Jisheng Zhang <[email-masked]>
Date: Tue, 30 Mar 2021 02:25:51 +0800

From: Jisheng Zhang <[email-masked]>

The core code manages the executable permissions of code regions of
modules explicitly, it is not necessary to create the module vmalloc
regions with RWX permissions. Create them with RW- permissions instead.
