Merge branch 'x86-traps' (trap handling from Andy Lutomirski)
Merge x86-64 iret fixes from Andy Lutomirski: "This addresses the following issues: - an unrecoverable double-fault triggerable with modify_ldt. - invalid stack usage in espfix64 failed IRET recovery from IST context. - invalid stack usage in non-espfix64 failed IRET recovery from IST context. It also makes a good but IMO scary change: non-espfix64 failed IRET will now report the correct error. Hopefully nothing depended on the old incorrect behavior, but maybe Wine will get confused in some obscure corner case" * emailed patches from Andy Lutomirski <luto@amacapital.net>: x86_64, traps: Rework bad_iret x86_64, traps: Stop using IST for #SS x86_64, traps: Fix the espfix64 #DF fixup and rewrite it in C
