Johannes Wikner c42a343158 x86/bugs: Skip RSB fill at VMEXIT ... commit 0fad2878642ec46225af2054564932745ac5c765 upstream. entry_ibpb() is designed to follow Intel's IBPB specification regardless of CPU. This includes invalidating RSB entries. Hence, if IBPB on VMEXIT has been selected, entry_ibpb() as part of the RET untraining in the VMEXIT path will take care of all BTB and RSB clearing so there's no need to explicitly fill the RSB anymore.
