Thanks for fixing these! I spent some time trying to automate the process of finding sensitive functions and eventually resorted into booting a kvm instance with a minimal initrd to test every single function in a clean and reproducible environment.
I found 7 more cases where calling register_kprobe() leads to an instant kernel panic:
__flush_tlb_single native_flush_tlb native_safe_halt native_set_pgd native_set_pmd native_set_pud native_write_cr0
You can see full kernel console output for each function at http://lindi.iki.fi/lindi/linux/kprobes/panics_2013-03-18/
