Subject: [PATCH 2/5] x86, debug: Add a collect-all misc debug checks option

From: Borislav Petkov <bp@...e.de>

Instead of adding a Kconfig debug option for every single aspect of x86
debugging code we have in the kernel, let's just simply add one which
people can enable and get all the debugging stuff switched on; boot and
test the resulting kernel and if they're satisfied, ship their patches.

This should save a lot of time of wading through "Kernel hacking" and
wondering what option to enable.
