[PATCH 2/2] powerpc: Add debug checks to catch invalid cpu-to-node mappings

2013-12-30 Thread Srivatsa S. Bhat
There have been some weird bugs in the past where the kernel tried to associate threads of the same core to different NUMA nodes, and things went haywire after that point (as expected). But unfortunately, root-causing such issues have been quite challenging, due to the lack of appropriate debug ch

[PATCH 1/2] powerpc: Fix the setup of CPU-to-Node mappings during CPU online

2013-12-30 Thread Srivatsa S. Bhat
On POWER platforms, the hypervisor can notify the guest kernel about dynamic changes in the cpu-numa associativity (VPHN topology update). Hence the cpu-to-node mappings that we got from the firmware during boot, may no longer be valid after such updates. This is handled using the arch_update_cpu_
