menuconfig SOUND
	tristate "Sound card support"
	depends on HAS_IOMEM
	help
	  If you have a sound card in your computer, i.e. if it can say more
	  than an occasional beep, say Y.  Be sure to have all the information
	  about your sound card and its configuration down (I/O port,
	  interrupt and DMA channel), because you will be asked for it.

	  You want to read the Sound-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>. General information about
	  the modular sound system is contained in the files
	  <file:Documentation/sound/oss/Introduction>.  The file
	  <file:Documentation/sound/oss/README.OSS> contains some slightly
	  outdated but still useful information as well.  Newer sound
	  driver documentation is found in <file:Documentation/sound/alsa/*>.

	  If you have a PnP sound card and you want to configure it at boot
	  time using the ISA PnP tools (read
	  <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
	  compile the sound card support as a module and load that module
	  after the PnP configuration is finished.  To do this, choose M here
	  and read <file:Documentation/sound/oss/README.modules>; the module
	  will be called soundcore.

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.

<div class='commit-subject'>PCI/ASPM: Handle PCI-to-PCIe bridges as roots of PCIe hierarchies</div><div class='commit-msg'>In a struct pcie_link_state, link-&gt;root points to the pcie_link_state of
the root of the PCIe hierarchy.  For the topmost link, this points to
itself (link-&gt;root = link).  For others, we copy the pointer from the
parent (link-&gt;root = link-&gt;parent-&gt;root).

Previously we recognized that Root Ports originated PCIe hierarchies, but
we treated PCI/PCI-X to PCIe Bridges as being in the middle of the
hierarchy, and when we tried to copy the pointer from link-&gt;parent-&gt;root,
there was no parent, and we dereferenced a NULL pointer:

  BUG: unable to handle kernel NULL pointer dereference at 0000000000000090
  IP: [&lt;ffffffff9e424350&gt;] pcie_aspm_init_link_state+0x170/0x820

Recognize that PCI/PCI-X to PCIe Bridges originate PCIe hierarchies just
like Root Ports do, so link-&gt;root for these devices should also point to
itself.
