If Linux/EBP causes an error that HV can't handle,
then instead of freezing the guest, HV injects the
error back into the guest. This enables the guest
to handle the error as gracefully as it can/needs.

1. sample handlers: minimal placeholder handlers that
just dump the error information on to the console. This

any error handler is registered. Its main responsibilities:
- map memory that's shared with HV where HV dumps all
information about the errors.
- register handlers for interrupts used by HV to inject
