[PATCH] x86: when L3 is present show its size in /proc/cpuinfo

[PATCH] x86: when L3 is present show its size in /proc/cpuinfo

The code that prints the cache size assumes that L3 always lives in chipset
and is shared across CPUs.  Which is not really true.

I think all the cachesizes reported by cpuid are in the processor itself.
The attached patch changes the code to reflect that.
