This fixes an -EPERM case where 'trace' was trying to use more than what configured on perf_event_mlock_kb. (Arnaldo Carvalho de Melo) Infrastructure: - Move bitops definitions so that they match the header file hierarchy in the kernel sources where that code came from. (Arnaldo Carvalho de Melo) - Adopt round{down,up}_pow_of_two from the kernel and use it instead of equivalent code, so that we reuse more kernel code and make tools/ look more like kernel source code, to encourage further contributions from kernel hackers (Arnaldo Carvalho de Melo) - Fix use after free in filename__read_build_id (Mitchell Krome) Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com> ---------------------------------------------------------------- Arnaldo Carvalho de Melo (17): perf evlist: Fixup brown paper bag on "hint" for --mmap-pages cmdline arg perf evlist: Clarify sterror_mmap variable names perf evlist: Improve the strerror_mmap method perf trace: Let the perf_evlist__mmap autosize the number of pages to use perf evlist: Do not use hard coded value for a mmap_pages default tools: Move __ffs implementation to tools/include/asm-generic/bitops/__ffs.h tools: Move code originally from linux/log2.h to tools/include/linux/ tools: Move code originally from asm-generic/atomic.h into tools/include/asm-generic/ tools: Whitespace prep patches for moving bitops.h tools lib: Move asm-generic/bitops/find.h code to tools/include and tools/lib tools: Introduce asm-generic/bitops.h tools: Move bitops.h from tools/perf/util to tools/ tools: Adopt fls_long and deps tools: Adopt rounddown_pow_of_two and deps perf tools: Make the mmap length autotuning more robust tools: Adopt roundup_pow_of_two perf evlist: Use roundup_pow_of_two Mitchell Krome (1): perf symbols: Fix use after free in filename__read_build_id tools/include/asm-generic/bitops.h | 27 +++++ tools/include/asm-generic/bitops/__ffs.h | 43 +++++++ tools/include/asm-generic/bitops/__fls.h | 1 + tools/include/asm-generic/bitops/atomic.h | 22 ++++ tools/include/asm-generic/bitops/find.h | 33 ++++++ tools/include/asm-generic/bitops/fls.h | 1 + tools/include/asm-generic/bitops/fls64.h | 1 + tools/include/linux/bitops.h | 53 +++++++++ tools/include/linux/log2.h | 185 ++++++++++++++++++++++++++++++ tools/lib/util/find_next_bit.c | 89 ++++++++++++++ tools/perf/MANIFEST | 13 ++- tools/perf/Makefile.perf | 14 ++- tools/perf/builtin-trace.c | 2 +- tools/perf/util/evlist.c | 46 ++++++-- tools/perf/util/include/linux/bitops.h | 162 -------------------------- tools/perf/util/symbol-minimal.c | 8 +- tools/perf/util/util.h | 29 ----- 17 files changed, 522 insertions(+), 207 deletions(-) create mode 100644 tools/include/asm-generic/bitops.h create mode 100644 tools/include/asm-generic/bitops/__ffs.h create mode 100644 tools/include/asm-generic/bitops/__fls.h create mode 100644 tools/include/asm-generic/bitops/atomic.h create mode 100644 tools/include/asm-generic/bitops/find.h create mode 100644 tools/include/asm-generic/bitops/fls.h create mode 100644 tools/include/asm-generic/bitops/fls64.h create mode 100644 tools/include/linux/bitops.h create mode 100644 tools/include/linux/log2.h create mode 100644 tools/lib/util/find_next_bit.c delete mode 100644 tools/perf/util/include/linux/bitops.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
