[PATCH] i386: remove redundant generic_identify() calls when identify…
Browse files Browse the repository at this point in the history
…ing cpus

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.
