Not all symbols are blacklisted on powerpc. Disable multiple_kprobes

This looks good to me, but could you try to find the functions
which should be blocked from kprobes?
(Usually, the function which are involved in the sw-breakpoint
handling, including locks etc.)

Yes, we did add several blacklists some time back, but there has been quite a bit of churn in our entry code. I've been meaning to audit it for a while now, but this has been blocking tests. It would be nice to skip this test for now until I am able to spend some time on this.

Thanks,
