------- Additional Comments From jkenisto at us dot ibm dot com  2006-11-16 18:07 -------
Further thoughts:
- vdso, not vtoc. (Haste and advanced age are a bad combo. :-})
- Since a kprobed instruction is copied into a kernel-space buffer and
single-stepped there, we do NOT want to allow kprobes on instructions that are
executed in user mode, such as on the vdso page.
