Andi Kleen c33d4568ac [PATCH] x86-64: Fix up handling of non canonical user RIPs
EM64T CPUs have somewhat weird error reporting for non canonical RIPs in
SYSRET.

We can't handle any exceptions there because the exception handler would
end up running on the user stack which is unsafe.

To avoid problems any code that might end up with a user touched pt_regs
should return using int_ret_from_syscall.  int_ret_from_syscall ends up
using IRET, which allows safe exceptions.
