Subject: Re: [PATCH 3/5] xen: replace TEST_COVERAGE with CONFIG_GCOV

FAOD my reading of xen/Kconfig.debug is that CONFIG_GCOV depends on
CONFIG_DEBUG which says

         This option is intended for development purposes
         only, and not for production use.

and is therefore out of security support.

Accordingly I think the only security review needed for the hypervisor
part is to check that everything is indeed disabled without
CONFIG_GCOV.

Thanks,
Ian.
