[Xen-devel] [PATCH v3 03/28] xen/public: Export cpu featureset information in the public API



For the featureset to be a useful object, it needs a stable interpretation, a
property which is missing from the current hw_caps interface.

Additionly, introduce TSC_ADJUST, FDP_EXCP_ONLY, SHA, PREFETCHWT1, ITSC, EFRO
and CLZERO which will be used by later changes.

To maintain compilation, FSCAPINTS is currently hardcoded at 9.  Future
changes will change this to being dynamically generated.

v3:
 * Allow the constants to be in a namespace of the includers choosing.
 * Add FDP_EXCP_ONLY

v2:
 * Rebase over upstream changes
 * Collect all feature introductions from later in the series
 * Restrict API to Xen and toolstack
