Recently, someone fixed a syntax error in the HTDMSOUND driver
introduced 4 years ago.

Unfortunately not by trying to compile this driver for his hardware but
by code inspection - which seems to be a strong indication that there
are no users left for this OSS sound driver.

This patch therefore removes it.

Grant Likely d26cd57071 [POWERPC] New registration for common Xilinx Virtex ppc405 platform devices
Currently virtex support in mainline make use of the infrastructure in
arch/ppc/syslib/ppc_sys.c for registering common devices on virtex ppc405
platforms.  The ppc_sys.c code is not well suited to the dynamic nature of
FPGA designs and makes adding new board ports more complex.  This patch
adds a new listing of common devices which does not depend on the ppc_sys.c
infrastructure.

Stefan Richter 70093cfde8 ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts
Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM.  As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.

This irritated or annoyed many users and distributors.  Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.

Therefore
  - remove the offending kernel config option
    IEEE1394_CONFIG_ROM_IP1394,
  - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
    loaded.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .

To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:

install ohci1394 /sbin/modprobe eth1394; \
                 /sbin/modprobe --ignore-install ohci1394

Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.
