[PATCH] oprofile: report anonymous region samples
The below patch passes samples from anonymous regions to userspace instead
of just dropping them. This provides the support needed for reporting
anonymous-region code samples (today: basic accumulated results; later:
Java and other dynamically compiled code).
As this changes the format, an upgrade to the just-released 0.9 release of
the userspace tools is required.
This patch is based upon an earlier one by Will Cohen <wcohen@redhat.com>
