tools headers: Synchronize sound/asound.h

To pick up the changes from this cset: 823dbb6eb08a ("ALSA: pcm: add SNDRV_PCM_FORMAT_{S,U}20") It doesn't affect how the tools are built, this os done just to silence this perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h' Right now tools/perf uses this header to generate string tables to translate ioctl commands in 'perf trace', see tools/perf/trace/beauty/sndrv_pcm_ioctl.sh, here is an example of a strace like system wide session, for one second: # perf trace -a -e ioctl sleep 1 0.000 ( 0.019 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 0.081 ( 0.006 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 0.092 ( 0.006 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_STATUS_EXT, arg: 0x7f6745ec4ae0) = 0 10.178 ( 0.013 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 10.229 ( 0.005 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 10.238 ( 0.013 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_STATUS_EXT, arg: 0x7f6745ec4ae0) = 0 10.368 ( 0.009 ms): threaded-ml/26440 ioctl(fd: 141, cmd: TIOCLINUX, arg: 0x7f8f70d2e1a4) = 0 10.495 ( 0.018 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 10.526 ( 0.005 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 19.695 ( 0.018 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 19.757 ( 0.006 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_HWSYNC, arg: 0x107b) = 0 19.767 ( 0.005 ms): alsa-sink-HDMI/4219 ioctl(fd: 47, cmd: SNDRV_PCM_STATUS_EXT, arg: 0x7f6745ec4ae0) = 0 # Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Maciej S.

tools/headers: Synchronize kernel ABI headers

2017-11-04T08:27:46Z

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.

We will use it to generate tables for beautifying ioctl's 'cmd' arg. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-wit4wwmrh9d37dtgtk0glbbj@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo
