   # HEAD: 2f7726f955572e587d5f50fbe9b2deed5334bd90 x86/fpu: Track AVX-512 usage of tasks

Three changes:

 - There's a preparatory patches for AVX state tracking that 
   computing-cluster folks would like to use for user-space batching - 
   but we are not happy about the related ABI yet so this is only the 
   kernel tracking side.

 - There's a cleanup for CR0 handling in do_device_not_available().

 - Plus we removed a workaround for an ancient binutils version.

 Thanks,

	Ingo
