file,\nevents, etc, so I untied these layers.\n\nThis reduces the complexity for the users as the number of\nparameters to most of the symbols and session APIs now was\nreduced while not adding more state to all the map instances by\nonly having data that is needed to split the kernel (kallsyms\nand ELF symtab sections) maps and do vmlinux relocation on the\nmain kernel map.\n\nSigned-off-by:

patch improves event scheduling by maximizing the use of PMU\nregisters regardless of the order in which events are created in a group.\n\nThe algorithm takes into account the list of counter constraints for each\nevent. It assigns events to counters from the most constrained, i.e.,\nworks on only one counter, to the least constrained, i.e., works on any\ncounter.\n\nIntel Fixed counter events and the BTS special event are also handled via\nthis algorithm which is designed to be fairly generic.\n\nThe patch also updates the validation of an event to use the scheduling\nalgorithm. This will cause early failure in perf_event_open().\n\nThe 2nd version of this patch follows the model used by PPC, by running\nthe scheduling algorithm and the actual assignment separately. Actual\nassignment takes place in hw_perf_enable() whereas scheduling is\nimplemented in hw_perf_group_sched_in() and x86_pmu_enable().\n\nSigned-off-by: Stephane Eranian
