Fields that generic_identify() sets unconditionally don't need pre- setting. (In fact the compiler removes some of those assignments anyway, at least in release builds.) With the setting of ->cpuid_level to -1 gone, also drop the respective BUG_ON() from default_init(). Signed-off-by: Jan Beulich <jbeulich@suse.com>
