[XEN PATCH v1 0/2] x86/CPU: optional build of Intel/AMD CPUs support

Posted by Sergiy Kibrik 3 months, 2 weeks ago

This series is one more step towards separation of Intel/AMD support in Xen.
With all preparation work is mostly done now, it becomes possible to make build
of arch/x86/cpu/{amd.c,intel.c} files optional, depending on whether
CONFIG_{AMD,INTEL} are enabled or not.

This can be useful for builds tuned for specific platform -- by reducing dead
code that won't ever be executed on that platform anyway.

Note: this series (namely its Intel part) depends on optional PSR support patch:
