[I/OAT]: Remove pci_module_init() from Intel I/OAT DMA engine
[I/OAT]: net/core/user_dma.c should #include <net/netdma.h>
[SCTP]: ADDIP: Don't use an address as source until it is ASCONF-ACKed
[SCTP]: Set chunk->data_accepted only if we are going to accept it.
[SCTP]: Verify all the paths to a peer via heartbeat before using them.
[SCTP]: Unhash the endpoint in sctp_endpoint_free().
[SCTP]: Check for NULL arg to sctp_bucket_destroy().
[PKT_SCHED] netem: Fix slab corruption with netem (2nd try)
[WAN]: Converted synclink drivers to use netif_carrier_*()
