[PATCH 0/3] x86/smpboot: Cleanup logical package ID

[Prarit Bhargava]

Andi posted two patches to clean up the logical package ID, and I posted a
bug fix for systems which boot with less than than the maximum core count.
If I take his changes into account the code base ends up with a significant
cleanup.  I am reposting his patches here.

I boot tested this using max_cpus and nr_cpus, as well as booting on
systems which would panic without the fix in 3/3.

Cleanup the logical package ID code by storing the logical package ID in
the cpuinfo_x86 struct and calculating the maximum logical package ID
after all the CPUs have been enumerated.
