tools/headers: Synchronize kernel ABI headers
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.
