i386: remove redundant generic_identify() calls when identifying cpus From: Magnus Damm cpu_dev->c_identify is only called from arch/i386/common.c:identify_cpu(), and this after generic_identify() already has been called. There is no need to call this function twice and hook it in c_identify - but I may be wrong, please double check before applying. This patch also removes generic_identify() from cpu.h to avoid unnecessary future nesting.
