Subject: [PATCH RT 0/2 v4] preempt-rt/x86: Handle sending signals from do_trap() by gdb

Thomas,

Can you apply these to v3.2-rt.

Version 4:
 In testing, Clark Williams triggered a bug in the paranoid_exit return
 path. The %rcx register was being clobbered by a function call and
 needed to be restored with: GET_THREAD_INFO(%rcx)

This version has been tested and so far has triggered no bugs.
