Changes in v3 from v2[2]:
	- Dropped mapping and unmapping of PPTT at runtime using
	  acpi_{get,put}_table() to avoid "BUG: sleeping function
	  called from invalid context"
	- Added tested-by from Geert

Changes in v2[2] from v1[1]:
        - Changed the cacheinfo per-cpu allocation to be atomic
	  to fix possible "BUG: sleeping function called from invalid context"
        - Added all the received tags

      cacheinfo: Use atomic allocation for percpu cache attributes
      ACPI: PPTT: Leave the table mapped for the runtime usage
      arch_topology: Fix cache attributes detection in the CPU hotplug path
