From c75bec79fc080039e4575a0f239ea7b111aabe88 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 11 Feb 2020 15:19:42 -0300 Subject: tools headers UAPI: Sync copy of arm64's asm/unistd.h with the kernel sources To get the changes in: 3e3c8ca5a351 ("arm64: Move __ARCH_WANT_SYS_CLONE3 definition to uapi headers") Silencing this tools/perf/ build warning: Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/unistd.h' differs from latest version at 'arch/arm64/include/uapi/asm/unistd.h' diff -u tools/arch/arm64/include/uapi/asm/unistd.h arch/arm64/include/uapi/asm/unistd.h Which will probably end up enabling the use of "clone3" in 'perf trace -e', haven't checked the build with this change on an arm64 system.
