[PATCH 0/5] uprobes/x86: cleanup validate_insn_* paths, fix X86_X32 case

[Oleg Nesterov]

Peter, feel free to ignore 1-4, but could you look at 5/5? It lacks the
test-case because I do not have a x32-ready testing machine.

So, what do you all think we should do with "callw"? Jim votes for
declining to probe callw, and I fully agree.

Any objection?

Until then, lets cleanup the validate_insn_* paths and fix another bug.
This cleanup can also simplify the next "reject callw" change.

Oleg.
