update_domains() merges the staged configuration changes into the
arch codes configuration array. Rename to make it clear its part of the

The filesystem code should calculate max_name_width for padding the
schemata file, move this to live with the code that will generate
the names.

After the filesystem code is moved, rdtgroup_pseudo_locked_in_hierarchy()
remains part of the x86 specific hooks to support psuedo lock. This code
walks each domain, and still does this after the separate resources are
merged.

Changes since v1:
* Added missing :

struct resctrl_schema.
Copying the value ensures there is no mismatch, but allows the filesystem
parts of resctrl to be modified to use the schema. Once the resources are
merged, the filesystem code can assign this value based on the schema
being created.

oo.
This difference means the type of the private pointers varies
between control and monitor info dirs.
If the flags are RF_MON_INFO, its a struct rdt_resource. If the
flags are RF_CTRL_INFO, its a struct resctrl_schema. Nothing in
res_common_files[] has both flags.

struct indicates where an abstraction is needed.
Splitting this structure only moves types around, and should not lead
to any change in behaviour.
