Merge tag 'x86_fpu_for_6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fpu updates from Dave Hansen:
 "There's no _actual_ kernel functionality here.

  This expands the documentation around AMX support including some code
  examples. The example code also exposed the fact that hardware
  architecture constants as part of the ABI, but there's no easy place
  that they get defined for apps. Adding them to a uabi header will
  eventually make life easier for consumers of the ABI.

  Summary:

   - Improve AMX documentation along with example code

   - Explicitly make some hardware constants part of the uabi"
