These are in priority order. Patch 1 could be folded into the patch it fixes. The selftests improve my confidence in the correctness of the whole pile. The next two patches fix IDTENTRY miswiring. The last two are optional and could easily wait until the next merge window.
Andy Lutomirski (6): x86/entry/compat: Clear RAX high bits on Xen PV SYSENTER x86/entry, selftests: Further improve user entry sanity checks x86/entry/xen: Route #DB correctly on Xen PV x86/entry/32: Fix #MC and #DB wiring on x86_32 x86/ldt: Disable 16-bit segments on Xen PV x86/entry: Rename idtentry_enter/exit_cond_rcu() to idtentry_enter/exit()
