kgdb: fix NMI hangs This patch fixes the hang regression with kgdb when the NMI interrupt comes in while the master core is returning from an exception. Adjust the NMI logic such that KGDB will not stop NMI exceptions from occurring by in general returning NOTIFY_DONE. It is not possible to distinguish the debug NMI sync vs the normal NMI apic interrupt so kgdb needs to catch the unknown NMI if it the debugger was previously active on one of the cpus.

x86: add the capability to print fuzzy backtraces For enhancing the 32 bit EBP based backtracer, I need the capability for the backtracer to tell it's customer that an entry is either reliable or unreliable, and the backtrace printing code then needs to print the unreliable ones slightly different. This patch adds the basic capability, the next patch will add a user of this capability.

x86: add a list for custom page fault handlers. Provides kernel modules a way to register custom page fault handlers. On every page fault this will call a list of registered functions. The functions may handle the fault and force do_page_fault() to return immediately. This functionality is similar to the now removed page fault notifiers. Custom page fault handlers are used by debugging and reverse engineering tools. Mmiotrace is one such tool and a patch to add it into the tree will follow. The custom page fault handlers are called earlier in do_page_fault() than the page fault notifiers were.
