commit ab45a0cc5d1cf522c1aef8f22ed512a9aae0dc1c
Author: Maynard Johnson <may...@us...>
Date:   Wed Feb 22 16:08:12 2012 -0600

    Symptom:  If runtime binaries have been stripped of symbol information, users
    must make debuginfo files available that contain the symbol information for
    those bianries so that opreport can attribute samples to symbols for those
    binaries.  But in a prelinked environment (e.g., RHEL, Fedora), opreport does
    not correctly process the debuginfo files, thus generating report data such
    as the following:
    
    samples  %        image name               symbol name
    1531      6.2205  libcairo.so.2.11000.2    /usr/lib64/libcairo.so.2.11000.2
    
    In the example given above, the debuginfo package corresponding to the cairo
    package has been installed.  Note that this problem only occurs where the
    runtime binary is completely stripped of symbol information.  So on RHEL and
    Fedora, basic  symbol information is retained in the runtime libc library, so
    this symptom does not appear with samples taken in libc.
    
    This patch reverts previous changes that actually broke this functionality.
    The changes being reverted are:
      - The SEC_LOAD filter
      - Calling translate_debuginfo_syms for all architectures
