  These series adds support few minor features.
1. Support assigning multiple tasks to control/mon groups in one command.
2. Add debug mount option for resctrl interface.
3. Add RMID and CLOSID in resctrl interface when mounted with debug option.
4. While doing these above changes, found that rftype flags needed some cleanup.
   They were named inconsistently. Re-arranged them much more cleanly now.
   Hope it can help future additions.

Code is built on top of tip branch x86/cache.

v2: Changes since v1
  a. Removed the changes to add the task's threads automatically. It required
     book keeping to handle the failures and gets complicated. Removed that change
     for now.
  b. Added -o debug option to mount in debug mode(comment from Fenghua)
  c. Added debug files rmid and closid. Stephane wanted to rename them more
     generic to accommodate ARM. It kind of loses meaning if is renamed differently.
     Kept it same for now. Will change if he feels strong about it. 

Babu Moger (7):
      x86/resctrl: Add multiple tasks to the resctrl group at once
      x86/resctrl: Remove few unnecessary rftype flags
      x86/resctrl: Rename rftype flags for consistency
      x86/resctrl: Re-arrange RFTYPE flags based on hierarchy
      x86/resctrl: Introduce -o debug mount option
      x86/resctrl: Display the RMID and COSID for resctrl groups
      x86/resctrl: Add debug files when mounted with debug option

It is in my queue. At the same time I hope that the
folks who pointed you into this direction would continue
to participate.
