Subject: [PATCH v13 0/8] powerpc: Further Strict RWX support
Date: Mon, 10 May 2021 11:18:20 +1000 [thread overview]
Message-ID: <20210510011828.4006623-1-jniethe5@gmail.com> (raw)
Adding more Strict RWX support on powerpc, in particular Strict Module RWX.
Thanks for all of the feedback everyone.
It is now rebased on linux-next + powerpc/64s/radix: Enable huge vmalloc mappings
