RE: [PATCH 1/2] x86/resctrl: Add io_alloc_min_cbm_all interface for CBM reset

Like this:

1) 	Read info files to figure out what minimum mask is needed for this system
2)	Use Babu's suggested syntax of
		# echo "L3:*={min_mask_from_step_1}" > schemata

Rather than Aaron's

	# echo "L3:*=0" > schemata

I'm OK with this for L3, but still see it being less useful for L2 with asymmetric domains.

It can meet the "set a minimum value across all domains" need.

But can fail setting a value that isn't supported by some of the domains.
