James Morse 141739aa73 x86/resctrl: Make ctrlval arrays the same size ... The CODE and DATA resources report a num_closid that is half the actual size supported by the hardware. This behaviour is visible to user-space when CDP is enabled. The CODE and DATA resources have their own ctrlval arrays which are half the size of the underlying hardware because num_closid was already adjusted. One holds the odd configurations values, the other even. Before the CDP resources can be merged, the 'half the closids' behaviour needs to be implemented by schemata_list_create(), but this causes the ctrl_val[] array to be full sized. Remove the logic from the architecture specific rdt_get_cdp_config() setup, and add it to schemata_list_create(). Functions that walk all the configurations, such as domain_setup_ctrlval() and reset_all_ctrls(), take num_closid directly from struct rdt_hw_resource also have to halve num_closid as only the lower half of each array is in use. domain_setup_ctrlval() and reset_all_ctrls() both copy struct rdt_hw_resource's num_closid to a struct msr_param. Correct the value here. This is temporary as a subsequent patch will merge all three ctrl_val[] arrays such that when CDP is in use, the CODA/DATA layout in the array matches the hardware. reset_all_ctrls()'s loop over the whole of ctrl_val[] is not touched as this is harmless, and will be required as it is once the resources are merged.
