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
