From: Joerg Roedel <jroedel@xxxxxxx> Hi, please find here the next iteration of my pending fixes for SEV-ES guest support in Linux. This version addresses the comments I received from Peter on the previous version, in particular: - Removed IRQ disable/enable calls in the ap-hlt loop code - Made __sev_get/put_ghcb() noinstr instead of __always_inline and put instrumentation_begin()/end() calls around panic() to fix an objtool warning. - Split up #DB handling in the #VC handler into a from-user and from-kernel part as well. The patches are again tested with a kernel with various debugging options enabled, running as an SEV-ES guest. The previous version of these patches can be found here: https://lore.kernel.org/lkml/20210616184913.13064-1-joro@xxxxxxxxxx/ Please review.
