  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
      x86/resctrl: Merge the CDP resources
      x86/resctrl: Make resctrl_arch_get_config() return its value
