Since commit cd1e6504 ("of/device: Don't register disabled devices"), the disabled device will not be registered at all. So we don't need to do the check again in the platform device driver. Signed-off-by:

When many pf_packet listeners are created on a lot of interfaces the current implementation using global packet type lists scales poorly. This patch adds per net_device packet type lists to fix this problem. The patch was originally written by Eric Biederman for linux-2.6.29. Tested on linux-3.16. Signed-off-by:

When IFLA_LINK_NETNSID is used, the netdevice should be built in this link netns and moved at the end to another netns (pointed by the socket netns or IFLA_NET_NS_[PID|FD]). Existing user of the newlink handler will use the netns argument (src_net) to find a link netdevice or to check some other information into the link netns. For example, to find a netdevice, two information are required: an ifindex (usually from IFLA_LINK) and a netns (this link netns). Note: when using IFLA_LINK_NETNSID and IFLA_NET_NS_[PID|FD], a user may create a netdevice that stands in netnsX and with its link part in netnsY, by sending a rtnl message from netnsZ.

TIME_WAIT sockets are not owning any skb. ip_send_unicast_reply() and tcp_v6_send_response() both use regular sockets. We can safely remove a test in sch_fq and save one cache line miss, as sk_state is far away from sk_pacing_rate. Tested at Google for about one year. Signed-off-by:

NET_ACT_CONNMARK fails to build if NF_CONNTRACK_MARK is disabled, and d7924450 ("act_connmark: Add missing dependency on NF_CONNTRACK_MARK") fixed that case, but missed the cased where NF_CONNTRACK is a loadable module. This adds the second dependency to ensure that NET_ACT_CONNMARK can only be built-in if NF_CONNTRACK is also part of the kernel rather than a loadable module. Signed-off-by:

The sock_iocb structure is allocate on stack for each read/write-like operation on sockets, and contains various fields of which only the embedded msghdr and sometimes a pointer to the scm_cookie is ever used. Get rid of the sock_iocb and put a msghdr directly on the stack and pass the scm_cookie explicitly to netlink_mmap_sendmsg. Signed-off-by:

NFC: 3.20 first pull request This is the first NFC pull request for 3.20. With this one we have: - Secure element support for the ST Micro st21nfca driver. This depends on a few HCI internal changes in order for example to support more than one secure element per controller. - ACPI support for NXP's pn544 HCI driver. This controller is found on many x86 SoCs and is typically enumerated on the ACPI bus there. - A few st21nfca and st21nfcb fixes. Signed-off-by:

Add the definition of a new callback that enable any PEAK-System CAN USB adapter to grant read access to its Bus Error Counters value. This ability is not supported by all the PEAK-System adapters, thus, for those, the callback pointer will be initiaized to NULL, which is correct regarding the linux-can device driver specs.

CAN to USB interfaces sold by the Swedish manufacturer Kvaser are divided into two major families: 'Leaf', and 'USBcanII'. From an Operating System perspective, the firmware of both families behave in a not too drastically different fashion. This patch adds support for the USBcanII family of devices to the current Kvaser Leaf-only driver. CAN frames sending, receiving, and error handling paths has been tested using the dual-channel "Kvaser USBcan II HS/LS" dongle. It should also work nicely with other products in the same category. List of new devices supported by this driver update: - Kvaser USBcan II HS/HS - Kvaser USBcan II HS/LS - Kvaser USBcan Rugged ("USBcan Rev B") - Kvaser Memorator HS/HS - Kvaser Memorator HS/LS - Scania VCI2 (if you have the Kvaser logo on top) Signed-off-by:Ahmed S.

This patch introduces run-time board detection through DMI and MAC-PHY configuration function used by quark_default_data() during initialization. It fills up the phy_addr for Galileo and Galileo Gen2 boards to indicate that the Ethernet MAC controller is or is not connected to any PHY. The implementation takes into consideration for future expansion in Quark series boards that may have different PHY address that is linked to its MAC controllers. This piece of work is derived from Bryan O'Donoghue's initial work for Quark X1000 enabling. Signed-off-by:

Struct mlx4_vhcr was implicitly padded by the gcc compiler on 64-bit architectures. This commit makes that padding explicit, to prevent issues with changing compilers and with incompatibilities between 32-bit architecture implicit padding and 64-bit architecture implicit padding. This structure is used in virtualization for communication between the Host and its Guests. The explicit padding allows 64-bit Hosts (old and new) to continue to interoperate with 64-bit Guests (old and new). However, without this fix, 64-bit Hosts could not interoperate with 32-bit Guests (since these did not insert the padding dword). With this fix, 32-bit Guests will be able to interoperate with 64-bit Hosts (since the structure offsets will be identical on both). Reported-by:

The firmware spec states that the timeout for all commands should be 60 seconds. In the past, the spec indicated that there were several classes of timeout (short, medium, and long). The driver has these different timeout classes. We leave the class differentiation in the driver as-is (to protect against any future spec changes), but set the timeout for all classes to be 60 seconds. In addition, we fix a few commands which had hard-coded numeric timeouts specified. Signed-off-by:

The reserved lKey is different for each VF. A base lkey value is returned in QUERY_DEV_CAP at offset 0x98. The reserved L_key value for a VF is: VF_lkey = base_lkey + (VF_number << 8). This VF L_key value should be returned in QUERY_FUNC_CAP (opcode-modifier = 0) at offset 0x48. To indicate that the lkey value at offset 0x48 is valid, the Hypervisor sets a flag bit in dword 0x0, offset 27 in the QUERY_FUNC_CAP wrapper function. When the VF calls QUERY_FUNC_CAP, it should check if this flag bit is set. If it is set, the VF should take the reserved lkey value at offset 0x48. If the bit is not set, the VF should not use a reserved lkey (i.e., should set its reserved lkey value to 0). Signed-off-by:
