perf_counter, powerpc, sparc: Fix compilation after perf_counter_overflow() change
Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow handling") removed the regs field from struct perf_sample_data and added a regs parameter to perf_counter_overflow(). This breaks the build on powerpc (and Sparc) as reported by Sachin Sant: arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart': arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializer This adjusts arch/powerpc/kernel/perf_counter.c to correspond with the new struct perf_sample_data and perf_counter_overflow().
