perf/x86/intel: Rename DMR offcore_rsp attribute to offmodule_rspgrafted
DMR introduces Offmodule Response events in place of the legacy Offcore Response events, but it still exposes the inherited offcore_rsp PMU attribute for programming the corresponding MSR data. Rename the DMR PMU attribute to offmodule_rsp so the sysfs interface matches the underlying event name and avoids user & tooling confusion.

+SELinux
+=======
+
+Information about the SELinux kernel subsystem can be found at the
+following links:
+
+ https://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux.git/tree/README.md
+
+ https://github.com/selinuxproject/selinux-kernel/wiki
+
+Information about the SELinux userspace can be found at:
+
+ https://github.com/SELinuxProject/selinux/wiki
+
+If you want to use SELinux, chances are you will want
+to use the distro-provided policies, or install the
+latest reference policy release from
+
+ https://github.com/SELinuxProject/refpolicy
+
+However, if you want to install a dummy policy for
+testing, you can do using ``mdp`` provided under
+scripts/selinux. Note that this requires the selinux
+userspace to be installed - in particular you will
+need checkpolicy to compile a kernel, and setfiles and
+fixfiles to label the filesystem.
+
+ 1. Compile the kernel with selinux enabled.
+ 2. Type ``make`` to compile ``mdp``.
+ 3. Make sure that you are not running with
+ SELinux enabled and a real policy. If
+ you are, reboot with selinux disabled
+ before continuing.
+ 4. Run install_policy.sh::
+
+ cd scripts/selinux
+ sh install_policy.sh
+
+Step 4 will create a new dummy policy valid for your
+kernel, with a single selinux user, role, and type.
+It will compile the policy, will set your ``SELINUXTYPE`` to
+``dummy`` in ``/etc/selinux/config``, install the compiled policy
+as ``dummy``, and relabel your filesystem.
