After the SPDX license tags were added a number of tooling headers got out of sync with their kernel variants, generating lots of build warnings. Sync them: - tools/arch/x86/include/asm/disabled-features.h, tools/arch/x86/include/asm/required-features.h, tools/include/linux/hash.h: Remove the SPDX tag where the kernel version does not have it. - tools/include/asm-generic/bitops/__fls.h, tools/include/asm-generic/bitops/arch_hweight.h, tools/include/asm-generic/bitops/const_hweight.h, tools/include/asm-generic/bitops/fls.h, tools/include/asm-generic/bitops/fls64.h, tools/include/uapi/asm-generic/ioctls.h, tools/include/uapi/asm-generic/mman-common.h, tools/include/uapi/sound/asound.h, tools/include/uapi/linux/kvm.h, tools/include/uapi/linux/perf_event.h, tools/include/uapi/linux/sched.h, tools/include/uapi/linux/vhost.h, tools/include/uapi/sound/asound.h: Add the SPDX tag of the respective kernel header. - tools/include/uapi/linux/bpf_common.h, tools/include/uapi/linux/fcntl.h, tools/include/uapi/linux/hw_breakpoint.h, tools/include/uapi/linux/mman.h, tools/include/uapi/linux/stat.h, Change the tag to the kernel header version: -/* SPDX-License-Identifier: GPL-2.0 */ +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */ Also sync other header details: - include/uapi/sound/asound.h: Fix pointless end of line whitespace noise the header grew in this cycle. - tools/arch/x86/lib/memcpy_64.S: Sync the code and add tools/include/asm/export.h with dummy wrappers to support building the kernel side code in a tooling header environment. - tools/include/uapi/asm-generic/mman.h, tools/include/uapi/linux/bpf.h: Sync other details that don't impact tooling's use of the ABIs.
