Bug description:
  Description:
  Customer report a Ubuntu kernel issue related to Intel BDX Core numbers setting
  Ubuntu 16.04.3  with kernel "4.10.0-32-generic_4.10.0-32.36~16.04.1_amd64"  hang if set "Cores Enabled" to 2 for both CPU.

  We have reproduced this issue on 17.10 release.

  With latest kernel, this issue disappears.

  now we bisect this issue is fixed by commit 947134d9b00f
  (“x86/smpboot: Do not use smp_num_siblings in __max_logical_packages
  calculation”) which was merged in v4.15-rc4.

  But after applying this commit to Ubuntu 16.04.3 kernel v4.13 code
  base or Linux upstream mainline kernel v4.13 code base, this issue
  still exists.

  Target Release: 16.04 / 17.10
