CONFIG_GCOV doesn't work with modules, and for various reasons it cannot work, see also https://lore.kernel.org/r/d36ea54d8c0a8dd706826ba844a6f27691f45d55.camel@sipsolutions.net Make CONFIG_GCOV depend on !MODULES to avoid anyone running into issues there. This also means we need not export the gcov symbols. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Richard Weinberger <richard@nod.at>

Write kernel log output directly to stdout.

This is useful for kernel debugging when your machine crashes very

early before the console code is initialized.
