[PATCH] i386/x86-64: Emulate CPUID4 on AMD
Intel systems report the cache level data from CPUID 4 in sysfs.
Add a CPUID 4 emulation for AMD CPUs to report the same
information for them. This allows programs to read this
information in a uniform way.
The AMD way to report this is less flexible so some assumptions
are hardcoded (e.g. no L3)
