-Subject: [PATCH] Fix dependencies between libcoregrind*.a and
- *m_main.o/*m_libcsetjmp.o
-
-The primary and secondary coregrind libraries must be updated
-when m_main.c or m_libcsetjmp.c are changed.
-
-A dependency was missing between libcoregrind*.a and libnolto_coregrind*.a,
-and so tools were not relinked when m_main.c or m_libcsetjmp.c were
-changed.

+Subject: [PATCH 1/2] valgrind: filter_xml_frames: do not filter /usr
+
+filter_xml_frames is intended to filter system paths under
+'/usr' that vary from platform to platform. In the ptest case
+for Yocto's valgrind, the ptest executables are placed under:
+   /usr/lib/valgrind/ptest
+and if these frames are filtered out, then the 'drd' tests fail
+the comparision between exepected and actual output.
+
+Changing this filter allows the comparison to succeed without
+any negative impact.

+Subject: [PATCH 2/2] valgrind: adjust std_list expected output
+
+The run-ptest script uses a custom --yocto-ptest option
+to change the summary statistics that valgrind issues
+to a format that matches what ptest-runner expects.
+
+Only this std_list test which checks that strcpy() works
+properly on Ubuntu-12.04 and later is affected by this change.
+It's normal output when called with --yocto-ptest is a blank
+line so adjust the expected output.
