From be709d48329a500621d2a05835283150ae137b45 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 25 Mar 2019 14:06:07 -0300 Subject: tools headers uapi: Sync asm-generic/mman-common.h and linux/mman.h To deal with the move of some defines from asm-generic/mmap-common.h to linux/mman.h done in: 746c9398f5ac ("arch: move common mmap flags to linux/mman.h") The generated mmap_flags array stays the same: $ tools/perf/trace/beauty/mmap_flags.sh static const char *mmap_flags[] = { [ilog2(0x40) + 1] = "32BIT", [ilog2(0x01) + 1] = "SHARED", [ilog2(0x02) + 1] = "PRIVATE", [ilog2(0x10) + 1] = "FIXED", [ilog2(0x20) + 1] = "ANONYMOUS", [ilog2(0x100000) + 1] = "FIXED_NOREPLACE", [ilog2(0x0100) + 1] = "GROWSDOWN", [ilog2(0x0800) + 1] = "DENYWRITE", [ilog2(0x1000) + 1] = "EXECUTABLE", [ilog2(0x2000) + 1] = "LOCKED", [ilog2(0x4000) + 1] = "NORESERVE", [ilog2(0x8000) + 1] = "POPULATE", [ilog2(0x10000) + 1] = "NONBLOCK", [ilog2(0x20000) + 1] = "STACK", [ilog2(0x40000) + 1] = "HUGETLB", [ilog2(0x80000) + 1] = "SYNC", }; $ And to have the system's sys/mman.h find the definition of MAP_SHARED and MAP_PRIVATE, make sure they are defined in the tools/ mman-common.h in a way that keeps it the same as the kernel's, need for keeping the Android's NDK cross build working.
