[PATCH 0/2] Fix x86 debug registers on FreeBSD with threads


The pan-BSD x86 debug register support code was only setting the
debug registers on the current LWP identified by inferior_ptid.
This fixes the code to set the debug registers on all of the LWPs
belonging to the current inferior on each change.

One question I have is that the amd64 x86 debug register code was 
invoking x86_cleanup_dregs in the mourn_inferior target op, but
the x86 linux native code calls this in the post_startup_inferior
target op instead.  Any ideas as to why they are different?

John Baldwin (2):
  Consolidate x86 debug register code for BSD native targets.
  Set debug registers on all threads belonging to the current inferior.
