Xiaochen Shen 2cc81c6992 x86/intel_rdt: Show missing resctrl mount options
In resctrl filesystem, mount options exist to enable L3/L2 CDP and MBA
Software Controller features if the platform supports them:

 mount -t resctrl resctrl [-o cdp[,cdpl2][,mba_MBps]] /sys/fs/resctrl

But currently only "cdp" option is displayed in /proc/mounts. "cdpl2" and
"mba_MBps" options are not shown even when they are active.

Before:
 # mount -t resctrl resctrl -o cdp,mba_MBps /sys/fs/resctrl
 # grep resctrl /proc/mounts
 /sys/fs/resctrl /sys/fs/resctrl resctrl rw,relatime,cdp 0 0

After:
 # mount -t resctrl resctrl -o cdp,mba_MBps /sys/fs/resctrl
 # grep resctrl /proc/mounts
 /sys/fs/resctrl /sys/fs/resctrl resctrl rw,relatime,cdp,mba_MBps 0 0

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
