Hi Keir and Tim,

The attached file enables flush-by-ASID for HVM. The patch mainly touches asid.c file to minimize the impacts on other HVM components. We also keep ASID interface intact by adding core_id as part of ASID comparison. Please refer to the patch description for design details.

This version was tested on real hardware successfully. Please review it.
