kconfig: Only generate config_is_xxx for bool and tristate options

    For strings and integers, the config_is_xxx macros are useless and
    sometimes misleading:

      #define CONFIG_INITRAMFS_SOURCE ""
      #define config_is_initramfs_source() 1

ASoC: davinci-pcm: comments for the conversion to BATCH mode

    In the previous commit 'ASoC: davinci-pcm: convert to BATCH mode', the phase
    offset of 2 was mentioned in the commit message but not well commented in the
    source.

    Add descriptive comments of the phase offset with and without ping-pong
    buffers enabled.

x86, build: Do not set the root_dev field in bzImage

    This has been obsoleted by the root= commandline and the rdev utility
    for many, many years.  People who still depend on this will surely
    have a copy of the rdev utility around, the rest of the world gets rid
    of another piece of buildhost-dependent data in the build. Thanks to
    Paul Bolle for the build.c cleanup.
