    Subject[PATCH 3.8 080/116] ALSA: compress: Cancel the optimization of compiler and fix the size of struct for all platform.
    Date
    3.8.13.27 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: "Wang, Xiaoming" <xiaoming.wang@intel.com>

    commit 2bd0ae464a6cf7363bbf72c8545e0aa43caa57f0 upstream.

    Cancel the optimization of compiler for struct snd_compr_avail
    which size will be 0x1c in 32bit kernel while 0x20 in 64bit
    kernel under the optimizer. That will make compaction between
    32bit and 64bit. So add packed to fix the size of struct
    snd_compr_avail to 0x1c for all platform.
