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"

Move the x86 documentation under Documentation/arch/ as a way of cleaning
up the top-level directory and making the structure of our docs more
closely match the structure of the source directories it describes.
All in-kernel references to the old paths have been updated.

As the first step in bringing some order to our architecture-specific
documentation, create a top-level arch/ directory and move arch.rst as its
index.rst file.
There is no change in the rendered docs at this point.
