| * Merge branch 'renesas/fixes' into renesas/socArnd Bergmann2012-03-154-3/+14
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fixes branch was merged into mainline just after v3.3-rc7, I'm merging it into this branch to fix up a nontrivial merge conflict. Unfortunately this means that we are now based on a commit between -rc releases, which we normally try to avoid.

This prevents a spurious overflow being picked up later and leading to either false accounting or a NULL dereference.

This is significant for non-sampling runs where it is possible for the new value to overtake the previous one, causing the delta to be out by up to max_period events. Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency") attempted to fix this problem by allowing interrupt handlers to pass an overflow flag to the event update function, causing the overflow calculation to assume that the counter passed through zero when going from prev to new. Unfortunately, this doesn't work when overflow occurs on the perf_task_tick path because we have the flag cleared and end up computing a large negative delta. This patch removes the overflow flag from armpmu_event_update and instead limits the sample_period to half of the max_period for non-sampling profiling runs.
