2008-01-28pasemi: DMA engine management libraryOlof Johansson
pasemi: DMA engine management library Introduce a DMA management library to manage the various DMA resources on the PA Semi SoCs. Since several drivers need to allocate these shared resources, provide some abstractions as well as allocation/free functions for channels, etc. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-01-28pasemi_mac: Move register definitions to include/asm-powerpcOlof Johansson
pasemi_mac: Move register definitions to include/asm-powerpc Move the common register formats and descriptor layouts from drivers/net/pasemi_mac.h to include/asm-poewrpc/pasemi_dma.h Previously only the ethernet driver was using them, but other drivers are coming up that will also use them, so it makes sense to share the constants.

2008-01-28[NETNS][DST]: Add the network namespace pointer in dst_opsDaniel Lezcano
The network namespace pointer can be stored into the dst_ops structure. This is usefull when there are multiple instances of the dst_ops for a protocol. When there are no several instances, this field will be never used in the protocol. So there is no impact for the protocols which do implement the network namespaces.

2008-01-28[NETNS][DST] dst: pass the dst_ops as parameter to the gc functionsDaniel Lezcano
The garbage collection function receive the dst_ops structure as parameter. This is useful for the next incoming patchset because it will need the dst_ops (there will be several instances) and the network namespace pointer (contained in the dst_ops). The protocols which do not take care of the namespaces will not be impacted by this change (expect for the function signature), they do just ignore the parameter.

Introduces the xt_connmark match revision 1. It uses fixed types, eventually obsoleting revision 0 some day (uses nonfixed types). (Unfixed types like "unsigned long" do not play well with mixed user-/kernelspace "bitness", e.g. 32/64, as is common on SPARC64, and need extra compat code.)

2008-01-28[IPV4]: Remove extra argument from arp_ignore.Denis V. Lunev
arp_ignore has two arguments: dev & in_dev. dev is used for inet_confirm_addr calling only. inet_confirm_addr, in turn, either gets in_dev from the device passed or iterates over all network devices if the device passed is NULL.

2008-01-28[NETNS]: Create ipv6 devconf-s for namespacesPavel Emelyanov
This is the core. Declare and register the pernet subsys for addrconf. The init callback the will create the devconf-s. The init_net will reuse the existing statically declared confs, so that accessing them from inside the ipv6 code will still work. The register_pernet_subsys() is moved above the ipv6_add_dev() call for loopback, because this function will need the net->devconf_dflt pointer to be already set.

2008-01-28[NEIGH]: Make /proc/net/arp opening consistent with seq_net_open semanticsDenis V. Lunev

2008-01-28[ATM]: Oops reading net/atm/arpDenis V. Lunev
cat /proc/net/atm/arp causes the NULL pointer dereference in the get_proc_net+0xc/0x3a. This happens as proc_get_net believes that the parent proc dir entry contains struct net. Fix this assumption for "net/atm" case. The problem is introduced by the commit c0097b07abf5f92ab135d024dd41bd2aada1512f from Eric W. Biederman/Daniel Lezcano. Signed-off-by: Denis V.
