From: Jiada Wang jiada_wang@mentor.com Date: Sun, 9 Apr 2017 20:02:37 -0700 Subject: perf tools: Fix build with ARCH=x86_64
From: Jiada Wang jiada_wang@mentor.com
commit 7a759cd8e8272ee18922838ee711219c7c796a31 upstream.
With commit: 0a943cb10ce78 (tools build: Add HOSTARCH Makefile variable) when building for ARCH=x86_64, ARCH=x86_64 is passed to perf instead of ARCH=x86, so the perf build process searchs header files from tools/arch/x86_64/include, which doesn't exist.
The following build failure is seen:
In file included from util/event.c:2:0: tools/include/uapi/linux/mman.h:4:27: fatal error: uapi/asm/mman.h: No such file or directory compilation terminated.
Fix this issue by using SRCARCH instead of ARCH in perf, just like the main kernel Makefile and tools/objtool's.
