Subject: [PATCH 0/3] x86/asm: More pinning
Date: Tue, 26 Feb 2019 15:36:44 -0800 [thread overview]
Message-ID: <20190226233647.28547-1-keescook@chromium.org> (raw)
This adds CR0 pinning (for WP), and cleans up the CR4 pin to avoid
taking an exception from WARN before fixing up the desired pin.
Additionally adds lkdtm test (which depends on the CR4 patch, otherwise
I'd send it via Greg's tree).
Thanks!
-Kees
