perf/core improvements and fixes:
User visible new features: - Add --buildid-all option to 'perf record' to avoid processing samples, just collecting build-ids for _all_ the DSOs that appears in PERF_RECORD_MMAP records (Namhyung Kim) - Add some more usage tips to appear in the hists browser (top & report) (Namhyung Kim, Andi Kleen) - Fix mmap2 event allocation in synthesize code, where we were allocating space just for PERF_RECORD_MMAP, the older variant, which could lead to corner case problems (Wang Nan) Developer stuff: - Make list.h self-sufficient, removing one more reference to kernel headers that lead to recent breakage when some rculist change was made in the kernel sources. (Josh Poimboeuf) Add missing NORETURN define for parse-options.h in tools/lib/subcmd (Josh Poimboeuf) - Fallback to srcdir/Documentation/ when not finding tips.txt elsewhere (Namhyung Kim) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWlT4QAAoJENZQFvNTUqpAc6MQAJpPJURHD4hqCznivvgdllUT fkKvIU5gDOqgNBTfxaqMECQhtT9mTKYpqFnWrHfBUdRic0172mD4Uu8unRBnqRb9 +Po8Tz2BXzKZkjiszNIEtuKbxnFN30Xl0twTrk+MKVZdxajoZzz/Z3ywzhMe9PYK Md5IHG1uBug0sP2ClPjdNPapDwwB3rYTtQXzl1tE/tFBUnLnjM9ey5LPAjCo9D7R nOl9pzT7tquvZ+lhubrnVwvfg7IYRsOhC1IpLcv2fJTfRkw3qv/+zZw3frrLXT9w U+Po+GHLkhgXyEBvBQ1nH+E4tfoGYm9Z/EinEnhNZ3AZLKHGqvUrIAXU9sL94Yg8 OytKPfgafPwm6TlQWR2lpFaLWypdMyV9Dljwc1gU9bVmDPyDX6bTAq+LYjdmAeOp 2gmspqNRcpO4FElxnXc23n5qS9idYC+rYKNUmGZqrArn5BEsOD54CVurY6cgalFv h4BNT7GrEV8uJa3VjmaTheZdGMgl3409KKPZhX1GMAejoC1fpgq0UXOnNscx97rN jYVynv7R7E2UrNTwS3MVFLouHyf2qk6n7IoxvTujom3jzRxOQSFb3E9K3JVo4qKd 3ri4yslHrS/1LAoJI1ZaRHGCTzEajbG3jaUsgY+dRBbUMsyhGa/qUooz1kJt1IYw 3dc2ZnfefdbOY6emgg+V =PXU/ -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: New, user visible features: - Add --buildid-all option to 'perf record' to avoid processing samples, just collecting build-ids for _all_ the DSOs that appears in PERF_RECORD_MMAP records (Namhyung Kim) - Add some more usage tips to appear in the hists browser (top & report) (Namhyung Kim, Andi Kleen) - Fix mmap2 event allocation in synthesize code, where we were allocating space just for PERF_RECORD_MMAP, the older variant, which could lead to corner case problems (Wang Nan) Infrastructure fixes: - Make list.h self-sufficient, removing one more reference to kernel headers that lead to recent breakage when some rculist change was made in the kernel sources.
