Subject: [PATCH 0/8] Fix year 2038 issue for sound subsystem

Since many structures will use timespec type variables to record time stamp
in uapi/asound.h, which are not year 2038 safe on 32bit system. This patchset
tries to introduce new structures removing timespec type to compatible native
mode and compat mode.

Moreover this patchset also converts the internal structrures to use timespec64
type and related APIs.

Arnd Bergmann (2):
  ALSA: move snd_pcm_ioctl_sync_ptr_compat into pcm_native.c
  ALSA: add new 32-bit layout for snd_pcm_mmap_status/control

Baolin Wang (6):
  ALSA: Replace timespec with timespec64
  ALSA: Avoid using timespec for struct snd_timer_status
  ALSA: Avoid using timespec for struct snd_ctl_elem_value
  ALSA: Avoid using timespec for struct snd_pcm_status
  ALSA: Avoid using timespec for struct snd_rawmidi_status
  ALSA: Avoid using timespec for struct snd_timer_tread
