Subject: [PATCH 2/5] x86, cacheinfo: it's not only cpuid 4 anymore
Since the code is now no longer only used for cpuid leaf 4 or an
emulation of it, rename everything that isn't really specific to cpuid 4
to cpuid_cacheinfo and the like. Also, rename cache_shared_cpu_map_setup()
to cache_shared_intel_cpu_map_setup() and move the vendor check into a
wrapper function. Pass default_attrs as argument to amd_l3_attrs().
This should make the code a bit less confusing and help splitting
intel_cacheinfo.c in a later patch.
