Hello Jason,
Just as promised, I'm resending the series after the merge window.
This patchset implements "kiosk" mode for KDB debugger. The mode reduces kdb features, so that it is no longer possible to leak sensitive data via the debugger, and not possible to change program flow in a predefined manner by an ordinary user. Root can control the capability.
There are a few patches, some are just cleanups, some are churn-ish cleanups, but inevitable. And the rest implements the mode -- after all the preparations, everything is pretty straightforward.
Thanks! Anton.
