ARM: 7357/1: perf: fix overflow handling for xscale2 PMUs
xscale2 PMUs indicate overflow not via the PMU control register, but by a separate overflow FLAG register instead. This patch fixes the xscale2 PMU code to use this register to detect to overflow and ensures that we clear any pending overflow when disabling a counter.
