Subject: [PATCH 00/12] Add the page size in the perf record (user tools)

From: Kan Liang <kan.liang@...ux.intel.com>

Current perf can report both virtual addresses and physical addresses,
but not the page size. Without the page size information of the utilized
page, users cannot decide whether to promote/demote large pages to
optimize memory usage.

The kernel patches have been merged into tip perf/core branch,
commit 8d97e71811aa ("perf/core: Add PERF_SAMPLE_DATA_PAGE_SIZE")
commit 76a5433f95f3 ("perf/x86/intel: Support PERF_SAMPLE_DATA_PAGE_SIZE")
commit 4cb6a42e4c4b ("powerpc/perf: Support PERF_SAMPLE_DATA_PAGE_SIZE")
commit 995f088efebe ("perf/core: Add support for PERF_SAMPLE_CODE_PAGE_SIZE")
commit 51b646b2d9f8 ("perf,mm: Handle non-page-table-aligned hugetlbfs")

and Peter's perf/core branch
commit 524680ce47a1 ("mm/gup: Provide gup_get_pte() more generic")
commit 44a35d6937d2 ("mm: Introduce pXX_leaf_size()")
commit 2f1e2f091ad0 ("perf/core: Fix arch_perf_get_page_size()")
commit 7649e44aacdd ("arm64/mm: Implement pXX_leaf_size() support")
commit 1df1ae7e262c ("sparc64/mm: Implement pXX_leaf_size() support")

This patch set is to enable the page size support in user tools.
