perf/core improvements and fixes:
- perf_mmap overwrite mode overhaul, prep work to get 'perf top' using it, making it bearable to use it in large core count systems such as Knights Landing/Mill Intel systems (Kan Liang) - s/390 now uses syscall.tbl, just like x86-64 to generate the syscall table id -> string tables used by 'perf trace' (Hendrik Brueckner) - Add perf vendor JSON metrics for ARM Cortex-A53 Processor (William Cohen) - Use strtoull() instead of home grown function (Andy Shevchenko) - Synchronize kernel ABI headers, v4.16-rc1 (Ingo Molnar) - Document missing 'perf data --force' option (Sangwon Hong) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEELb9bqkb7Te0zijNb1lAW81NSqkAFAlqFhnIACgkQ1lAW81NS qkCWiA/+MKuwFS/NiVBKRRmlBTEUHPo3zmOA3lPV4sJcf2qIicQKjpSTCdC8yTrM 4Br9q3x211Zk1XxcRrB6urTT/8ySzkfo2sbKLRbJfvj5MT5rJ+wcVAJ3KLLoI2xF daDqrCMMP9otMcyiJUx9I88FagS2XkmL2r3M8O7z/9PzIegYLYSB5v2YwAoNVkJa odA1JTXChIB0KM980cY3NvrhlV++uPIVdv32q0MWhIdqExFWcl4Qct3ax6WztOeG QedMpFsEoAtjn+l8w9cc6l61vKiizCZaWvs/mgYZ2xaaWTwKGxm89W81KDYn9Kuq fZEkq/tDoy/0ehqZtaPMxjoH63FpYuMfsW557b7w21RDYo+M788D0yYnvBd63Fp3 ptBgiLGZ2lHKEPrDab+6fVjIx0eEwXFVeuUniDWJ1ocTnyOoSna2nPzNF2cpEYaO hyiA+1McR3hf7x6l8wykzJ8f/HrPVeY+PgbBL1i6nZIJiDkqFfQ52/MjtAzD9ONJ kuKRIgCPGmD1+8z1/dTA4tgXZNbbCH+F05/G26hzcZjNTXam44/CjaA+0sfxD+jc 3mVHTbPiHf6zJfFap7OmcJOcn+QEcRNajvHU1Eci6pwClMwrkhFH79hMbPkcewU9 eqLQXkqrhitAEn5n2qirTT3CJZIZ65m6SM68rl9bYnShMsiyqNE= =TdvB -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.17-20180215' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core fixes from Arnaldo Carvalho de Melo: - perf_mmap overwrite mode fixes/overhaul, prep work to get 'perf top' using it, making it bearable to use it in large core count systems such as Knights Landing/Mill Intel systems (Kan Liang) - s/390 now uses syscall.tbl, just like x86-64 to generate the syscall table id -> string tables used by 'perf trace' (Hendrik Brueckner) - Use strtoull() instead of home grown function (Andy Shevchenko) - Synchronize kernel ABI headers, v4.16-rc1 (Ingo Molnar) - Document missing 'perf data --force' option (Sangwon Hong) - Add perf vendor JSON metrics for ARM Cortex-A53 Processor (William Cohen) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
