Message-ID: <tip-td9t5vhjltqnlzaurkkgq8cn@git.kernel.org> Date: Sat, 21 Apr 2018 00:50:28 -0700 From: tip-bot for Arnaldo Carvalho de Melo <tipbot@...or.com> To: linux-tip-commits@...r.kernel.org Cc: hpa@...or.com, tglx@...utronix.de, mingo@...nel.org, linux-kernel@...r.kernel.org, torvalds@...ux-foundation.org, namhyung@...nel.org, wangnan0@...wei.com, jolsa@...nel.org, acme@...hat.com, dsahern@...il.com, mhocko@...e.com, adrian.hunter@...el.com Subject: [tip:perf/urgent] perf trace: Support MAP_FIXED_NOREPLACE Commit-ID: 4e5c01a7c746130033eb6e7153b346b8ca61e7a5 Gitweb: https://git.kernel.org/tip/4e5c01a7c746130033eb6e7153b346b8ca61e7a5 Author: Arnaldo Carvalho de Melo <acme@...hat.com> AuthorDate: Mon, 16 Apr 2018 16:39:38 -0300 Committer: Arnaldo Carvalho de Melo <acme@...hat.com> CommitDate: Wed, 18 Apr 2018 15:34:52 -0300 perf trace: Support MAP_FIXED_NOREPLACE Introduced in a4ff8e8620d3 ("mm: introduce MAP_FIXED_NOREPLACE"), and now that we have that define in the just syncronized tools/arch/*/include/uapi/asm/mman.h files, add support for it. This should really transition to autogeneration of string tables as done for various other things: $ ls /tmp/build/perf/trace/beauty/generated/*.c arch_errno_name_array.c kcmp_type_array.c madvise_behavior_array.c pkey_alloc_access_rights_array.c prctl_option_array.c $ head /tmp/build/perf/trace/beauty/generated/madvise_behavior_array.c static const char *madvise_advices[] = { [0] = "NORMAL", [1] = "RANDOM", [2] = "SEQUENTIAL", [3] = "WILLNEED", [4] = "DONTNEED", [8] = "FREE", [9] = "REMOVE", [10] = "DONTFORK", [11] = "DOFORK", $ Till then, add support for this the old way. Also it has to be ifdef'ed, because arches like mips still don't define it. The proper solution will be to have per-arch tables for these values to support cross-analysis.
