Julian Vetter ad6639f143 sound: Make CONFIG_SND depend on INDIRECT_IOMEM instead of UML 
When building for the UM arch and neither INDIRECT_IOMEM=y, nor
HAS_IOMEM=y is selected, it will fall back to the implementations from
asm-generic/io.h for IO memcpy. But these fall-back functions just do a
memcpy. So, instead of depending on UML, add dependency on 'HAS_IOMEM ||
INDIRECT_IOMEM'.

config SOUND_OSS_CORE bool default n

config SOUND_OSS_CORE_PRECLAIM bool "Preclaim OSS device numbers" depends on SOUND_OSS_CORE default y help With this option enabled, the kernel will claim all OSS device numbers if any OSS support (native or emulation) is enabled whether the respective module is loaded or not and try to load the appropriate module using sound-slot/service-* and char-major-* module aliases when one of the device numbers is opened. With this option disabled, kernel will only claim actually in-use device numbers and opening a missing device will generate only the standard char-major-* aliases.

  The only visible difference is use of additional module aliases
  and whether OSS sound devices appear multiple times in
  /proc/devices.  sound-slot/service-* module aliases are scheduled
  to be removed (ie. PRECLAIM won't be available) and this option is
  to make the transition easier.  This option can be overridden
  during boot using the kernel parameter soundcore.preclaim_oss.

  Disabling this allows alternative OSS implementations.

  If unsure, say Y.

config AC97_BUS tristate help This is used to avoid config and link hard dependencies between the sound subsystem and other function drivers completely unrelated to sound although they're sharing the AC97 bus. Concerned drivers should "select" this.
