H A D | cputhreads.h | diff d52356e7f48e400ca258c6763a232a92fa82ff68 Tue Mar 31 11:11:46 CDT 2015 Jan Stancek <jstancek@redhat.com> powerpc: fix memory corruption by pnv_alloc_idle_core_states
Space allocated for paca is based off nr_cpu_ids, but pnv_alloc_idle_core_states() iterates paca with cpu_nr_cores()*threads_per_core, which is using NR_CPUS.
This causes pnv_alloc_idle_core_states() to write over memory, which is outside of paca array and may later lead to various panics.
