A bug was introduced during a respin of: commit 57a4a11b target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0 This patch introduced two calls to get_pmceid() during CPU initialization - one each for PMCEID0 and PMCEID1. In addition to building the register values, get_pmceid() clears an internal array mapping event numbers to their implementations (supported_event_map) before rebuilding it. This is an optimization since much of the logic is shared. However, since it was called twice, the contents of supported_event_map reflect only the events in PMCEID1 (the second call to get_pmceid()). Fix this bug by moving the initialization of PMCEID0 and PMCEID1 back into a single function call, and name it more appropriately since it is doing more than simply generating the contents of the PMCEID[01] registers.
