The new sample type, PERF_SAMPLE_DATA_PAGE_SIZE, requires the virtual

The large PEBS is disabled with the sample type, because perf doesn't
support munmap tracking yet. The PEBS buffer for large PEBS cannot be
flushed for each munmap. Wrong page size may be calculated. The large
PEBS can be enabled later separately when munmap tracking is supported.
You also get to fix up Power.
arch/powerpc/perf/core-book3s.c: (PERF_SAMPLE_ADDR |
PERF_SAMPLE_PHYS_ADDR))
Sure. I will add one patch for Power.
Thanks,
