Hi Linus,

Please pull some x86/fpu changes for 6.4. 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.
