Konstantin Belousov 4cc6942f37 Change the way the lcall $7,$0 is reflected to usermode. Instead of ... setting call gate, which must be 64 bit, put a code segment descriptor into ldt slot 0. This way, syscall shim does not switch temporary to 64bit trampoline, and does not create a window where signal delivery interrupts 64 bit mode (signal handler cannot return). The cost is shim running with non-zero based segment in %cs, which requires vfork() handling make more assumptions. Sponsored by: The FreeBSD Foundation MFC after: 1 week		2014-12-27 23:19:08 +00:00
