One problem with frequency driven counters is that we cannot predict the rate at which they trigger, therefore we have to start them at period=1, this causes a ramp up effect.

This patch improves event scheduling by maximizing the use of PMU registers regardless of the order in which events are created in a group. The algorithm takes into account the list of counter constraints for each event. It assigns events to counters from the most constrained, i.e., works on only one counter, to the least constrained, i.e., works on any counter. Intel Fixed counter events and the BTS special event are also handled via this algorithm which is designed to be fairly generic. The patch also updates the validation of an event to use the scheduling algorithm. This will cause early failure in perf_event_open(). The 2nd version of this patch follows the model used by PPC, by running the scheduling algorithm and the actual assignment separately. Actual assignment takes place in hw_perf_enable() whereas scheduling is implemented in hw_perf_group_sched_in() and x86_pmu_enable().

When running perf across all cpus with backtracing (-a -g), sometimes we get samples without associated backtraces: 23.44% init [kernel] [k] restore 11.46% init eeba0c [k] 0x00000000eeba0c 6.77% swapper [kernel] [k] .perf_ctx_adjust_freq 5.73% init [kernel] [k] .__trace_hcall_entry 4.69% perf libc-2.9.so [.] 0x0000000006bb8c | |--11.11%-- 0xfffa941bbbc It turns out the backtrace code has a check for the idle task and the IP sampling does not. This creates problems when profiling an interrupt heavy workload (in my case 10Gbit ethernet) since we get no backtraces for interrupts received while idle (ie most of the workload). Right now x86 and sh check that current is not NULL, which should never happen so remove that too. Idle task's exclusion must be performed from the core code, on top of perf_event_attr:exclude_idle.

On a given architecture, when hardware breakpoint registration fails due to un-supported access type (read/write/execute), we lose the bp slot since register_perf_hw_breakpoint() does not release the bp slot on failure.
