Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

Description:	Parameters for the CPU cache attributes



		allocation_policy:

			- WriteAllocate: allocate a memory location to a cache line

					 on a cache miss because of a write

			- ReadAllocate: allocate a memory location to a cache line

					on a cache miss because of a read

			- ReadWriteAllocate: both writeallocate and readallocate



		attributes: LEGACY used only on IA64 and is same as write_policy



		coherency_line_size: the minimum amount of data in bytes that gets

				     transferred from memory to cache



		level: the cache hierarcy in the multi-level cache configuration



		number_of_sets: total number of sets in the cache, a set is a

				collection of cache lines with the same cache index



		physical_line_partition: number of physical cache line per cache tag



		shared_cpu_list: the list of logical cpus sharing the cache



		shared_cpu_map: logical cpu mask containing the list of cpus sharing

				the cache



		size: the total cache size in kB



		type:

			- Instruction: cache that only holds instructions

			- Data: cache that only caches data

			- Unified: cache that holds both data and instructions



		ways_of_associativity: degree of freedom in placing a particular block

					of memory in the cache



		write_policy:

			- WriteThrough: data is written to both the cache line

					and to the block in the lower-level memory

			- WriteBack: data is written only to the cache line and

				     the modified cache line is written to main

				     memory only when it is replaced
