# HEAD: 2066f00e5b2dc061fb6d8c88fadaebc97f11feaa x86/topology: Implement topology_is_core_online() to address SMT regression

Fix a CPU topology code regression that caused the mishandling
of certain boot command line options, and re-enable CONFIG_PTDUMP
on i386 that was mistakenly turned off in the Kconfig.

Thanks,

Ingo
