Inside of tarbal (README file) and copied below I put short description of each patch. Some of patches are Cisco specific and may not be any interest for you. Some like MIPS support, cross compilation improvements, misc general fixes (i.e systemtap issue 6977), I think, could be quite useful to community. Since it is quilt patch series and patches may have patch apply order issues, we are publishing all of them, exactly as we use/apply them, regardless whether we consider them Cisco specific or not.

Latter as time permits, I can work on cleaning them up, moving to latest systemtap git and try to prepare them for commit into systemtap tree. It would be great if folks could take a look at patches and/or patches description and indicate priorities/interests for specific patches on which I could start working first.

Hi All,

Last week I was on vacation, playing around with a MIPS base creator
board (http://www.elinux.org/MIPS_Creator_CI20), and seeing if I could
get systemtap running on it. After locally building the linux-3.0.8
kernel I was able to massage the systemtap-mips.patch from
https://sourceware.org/ml/systemtap/2012-q4/msg00084.html, so that
current systemtap is buildable and able to run a portion of the
testsuite on MIPS. Attached is the current modified patch. The tests hung in
the ./systemtap.base/limits.stp tests and a number of tests failed
because of issues with utrace functions not being found. The
systemtap.sum is also attached to this email.
