| |
From: Fenghua Yu <fenghua.yu@intel.com>
There was a cut & paste error when adding code to update the per-cpu closid when changing the bitmask of CPUs to an rdt group. CPUs removed from the group were correctly given back to the default group. But CPUs added to the group should be given the closid of their new group, not the default group closid.
Fixes: f410770293a1 ("x86/intel_rdt: Update percpu closid immeditately on CPUs affected by changee")
