Hi Andrew, After merging the akpm tree, today's linux-next build (powerpc_le perf) failed like this: bench/numa.c:37:10: fatal error: linux/numa.h: No such file or directory #include ^~~~~~~~~~~~~~ Caused by patches "mm: replace all open encodings for NUMA_NO_NODE" "mm-replace-all-open-encodings-for-numa_no_node-fix" For linux/numa.h to be generally availble to the tools builds, it must be copied into tools/include/linux ... I have done that copy for today: From 6dabc11d5513510d0ec0a6b0a4aa8b9051b71516 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 3 Dec 2018 17:57:27 +1100 Subject: [PATCH] linux/numa.h is now needed for the perf build Signed-off-by: Stephen Rothwell --- tools/include/linux/numa.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 tools/include/linux/numa.h diff --git a/tools/include/linux/numa.h b/tools/include/linux/numa.h new file mode 100644 index 000000000000..110b0e5d0fb0 --- /dev/null +++ b/tools/include/linux/numa.h @@ -0,0 +1,16 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _LINUX_NUMA_H +#define _LINUX_NUMA_H + + +#ifdef CONFIG_NODES_SHIFT +#define NODES_SHIFT CONFIG_NODES_SHIFT +#else +#define NODES_SHIFT 0 +#endif + +#define MAX_NUMNODES (1 << NODES_SHIFT) + +#define NUMA_NO_NODE (-1) + +#endif /* _LINUX_NUMA_H */ -- 2.19.1 -- Cheers, Stephen Rothwell
