Hi all,

        here is a list of all changes between 1.0.5a and 1.0.6a release.
The 1.0.6a driver package fixes the /proc problem with loading of the 
sequencer client modules.

* alsa-driver
  - core
    - fixed the detection of x86-64 arch
    - 2.6 kernel sync - mostly __user stuff
    - This patch removes snd_kcalloc() from the kernel and updates callers to
      use the new generic kcalloc().
    - Removal and replacement of magic memory allocators and casts
    - Clean up of obsolete MODULE_* stuff (core part)
      - Removed MODULE_CLASSES() and MODULE_SYNTAX().
    - Clean up the PCI resource allocation.
    - Clean up the suspend/resume: save/restore of pci state
    - use ARRAY_SIZE() instead of sizeof() computations
    - Clean up: removed ifdefs and obsolete codes.
    - Unlock BKL in ioctl callback to avoid the long preempt-disabling.
    - Clean up DMA buffer allocation routines.
    - Fix up sound driver proc-reading interfaces.
  - PCM midlevel
    - stack usage reduction
    - Clean up and optimization of PCM format-specific functions
    - Clean up the buffer management in the PCM runtime record
    - Fix the mmap via io_remap_page_range() on nm256, rme32 and rme96.
      Added SNDRV_PCM_INFO_MMAP_IOMEM to handle this case.
    - Clean up the indirect accessing on RME32/RME96 drivers.
    - Clean up of indirect PCM data transfer with helper functions.
    - snd_pcm_timer_resolution_change() - better precision
    - The PCM prepare callback is now non-atomic, so that the driver can
      use the functions calling schedule (e.g. kmalloc with GFP_KERNEL).
    - Fixed/improved XRUN detection
      - don't print XRUN message in the case of draining.
      - pointer callback can return SNDRV_PCM_POS_XRUN to notify the middle layer.
    - ioctl32 - Added the wrapper for sync_ptr and hwsync ioctls.
    - Serialize runtime->status->state access
  - PCM OSS emulation
    - reduce stack usage
  - sequencer
