[PATCH 0/4 v2] Implement support for SystemTap probes on userspace

[Sergio Durigan Junior]

Hello again,

Sorry for the long delay to resubmit these patches.  Well, here they
are, with all comments addressed.  I will CC: the people who have made
comments in the last attempt.

Here is a full explanation of what these patches are supposed to do:

   http://sourceware.org/ml/gdb-patches/2012-03/msg00353.html

I regtested all of the components of this patch in a x86_64, PPC64,
S390x and ARM archs, without regressions.

Comments and reviews are welcome.  This time, I promise I'll resubmit
the patches in a shorter time :-).

Thank you,
