Undefined behaviour with get_cpu_vendor

[Christian Ehrhardt <ehrhardt@mathematik.uni-ulm.de>]

Hi,

Your Patch at (URL wrapped)

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git; \
		a=commit;h=99c6e60afff8a7bc6121aeb847dab27c556cf0c9

introduced an additional Parameter (int early) to get_cpu_vendor.
However, the same function is called in arch/i386/kernel/apic.c (via
an explicit extern declaration that doesn't have the new early parameter.

I don't know if this can cause actual problems but I think something like
the patch below is needed for correctness.

   regards    Christian
