[PATCH 0/7] KDB: Kiosk (reduced capabilities) mode

[Anton Vorontsov]

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.
