to implement oneshot behavior when they woke the system from sleeep:
forcibly disable the alarm, just in case.

The acpi idle waits calls local_irq_save and then uses mwait to go into
idle. The tracer gets reenabled at local_irq_save but does not detect that
the idle allows for wake ups.
This patch adds code to disable the tracing when acpi puts the CPU to idle.

Removes legacy reinvent-the-wheel type thing. The generic
machinery integrates much better to automated debugging aids
such as kerneloops.org (and others), and is unambiguous due to
better naming. Non-intuively BUG_TRAP() is actually equal to
WARN_ON() rather than BUG_ON() though some might actually be
promoted to BUG_ON() but I left that to future.
I could make at least one BUILD_BUG_ON conversion.

This module harvests more than just memory errors, it also harvests
various bus and dma errors that the Chipset detects. Previously, it would
report all such errors, which would cause output to be TOO loud.
This patches therefore adds a parameter which is used to turn off
NON-MEMORY error reports by default. Or the reporting can be enabled via
the parameter
Also did code style cleanup: less than 80 characters per line rule
