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.
