Subject: [PATCH v2 0/2] x86/cacheinfo: Set the number of leaves per CPU

Hi,

This v2 of now a patchset to set the number of cache leaves independently
for each CPU. v1 can be found here [1].

These are the changes since v2:
  * Dave Hansen, suggested to use the existing per-CPU ci_cpu_cacheinfo
    variable. Now the global variable num_cache_leaves became useless.
  * While here, I noticed that init_cache_level() also became useless:
    x86 does not need ci_cpu_cacheinfo::num_levels.

These patches apply cleanly on top of the master branch of the tip tree.

Thanks and BR,
Ricardo
