i386: remove redundant generic_identify() calls when identifying 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.

This patch also removes generic_identify() from cpu.h to avoid unnecessary future nesting.

There are sometimes subtle interactions with this (e.g. with parameters changing flags and then someone else overwriting them again)

But agreed it seems bogus to call it twice.

I guess the only way to find out how much it breaks is to merge it.

i386: mark cpu_dev structures as __cpuinitdata

The different cpu_dev structures are all used from __cpuinit callers what I can tell. So mark them as __cpuinitdata instead of __initdata. I am a little bit unsure about arch/i386/common.c:default_cpu, especially when it comes to the purpose of this_cpu.

PATCH 6/6 x86_64: mark init_amd() as __cpuinit

In reply to Magnus Damm

The init_amd() function is only called from identify_cpu() which is already marked as __cpuinit. So let's mark it as __cpuinit.
