   # HEAD: 47ff30cc1be7bf426c03ecc84371452109b416e4 x86/percpu: Enable named address spaces for all capable GCC versions

x86/percpu changes for v6.11:

 - Enable the named address spaces based percpu accessors optimization
   on all GCC versions that contain this feature, detected through
   a build-time testcase. This effectively enables the feature on
   GCC 6, GCC 7 and GCC 8 versions.

 - Fix operand constraint modifier in __raw_cpu_write()

 - Reorganize the per-CPU headers for better readability

 - Misc cleanups and fixes

 Thanks,

	Ingo
