[PATCH 2/3] powerpc/numa: Early request for home node associativity

2019-08-22 Thread Srikar Dronamraju
Currently the kernel detects if its running on a shared lpar platform and requests home node associativity before the scheduler sched_domains are setup. However between the time NUMA setup is initialized and the request for home node associativity, workqueue initializes its per node cpumask. The
