This patch removes the redundant sysfs cacheinfo code by reusing
the newly introduced generic cacheinfo infrastructure through the
commit 246246cbde5e ("drivers: base: support cpu cache information
interface to userspace via sysfs")

The private pointer provided by the cacheinfo is used to implement
the AMD L3 cache specific attributes.

Sorry for late response, was on vacation.
I have fixed this issue now and will post the new version soon.
Thanks a lot for trying it out.
