x86/resctrl: Make resctrl_arch_get_config() return its value (2021-08-11 18:42:53 +0200)

- A first round of changes towards splitting the arch-specific bits from
the filesystem bits of resctrl, the ultimate goal being to support ARM's
equivalent technology MPAM, with the same fs interface (James Morse)

James Morse (25):
x86/resctrl: Split struct rdt_resource
x86/resctrl: Split struct rdt_domain
x86/resctrl: Add a separate schema list for resctrl
x86/resctrl: Pass the schema in info dir's private pointer
x86/resctrl: Label the resources with their configuration type
x86/resctrl: Walk the resctrl schema list instead of an arch list
x86/resctrl: Store the effective num_closid in the schema
x86/resctrl: Add resctrl_arch_get_num_closid()
x86/resctrl: Pass the schema to resctrl filesystem functions
x86/resctrl: Swizzle rdt_resource and resctrl_schema in pseudo_lock_region
x86/resctrl: Add a helper to read/set the CDP configuration
x86/resctrl: Move the schemata names into struct resctrl_schema
x86/resctrl: Group staged configuration into a separate struct
x86/resctrl: Allow different CODE/DATA configurations to be staged
x86/resctrl: Rename update_domains() to resctrl_arch_update_domains()
x86/resctrl: Add a helper to read a closid's configuration
x86/resctrl: Pass configuration type to resctrl_arch_get_config()
x86/resctrl: Make ctrlval arrays the same size
x86/resctrl: Apply offset correction when config is staged
x86/resctrl: Calculate the index from the configuration type
x86/resctrl: Merge the ctrl_val arrays
x86/resctrl: Remove rdt_cdp_peer_get()
x86/resctrl: Expand resctrl_arch_update_domains()'s msr_param range
