2015-03-24filter: introduce SKF_AD_VLAN_TPID BPF extensionMichal Sekletar
If vlan offloading takes place then vlan header is removed from frame and its contents, both vlan_tci and vlan_proto, is available to user space via TPACKET interface. However, only vlan_tci can be used in BPF filters. This commit introduces a new BPF extension. It makes possible to load the value of vlan_proto (vlan TPID) to register A. Support for classic BPF and eBPF is being added, analogous to skb->protocol.

2015-03-20net: netcp: ethss: enhancement to support NetCP 1.5 ethssWingMan Kwok
NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3 variants of the ethss subsystem, 9 port, 5 port and 2 port. These have one host port towards the CPU and N external slave ports. To customize the driver for these new ethss sub systems, multiple compatibility strings are introduced. Currently some of parameters that are different on different variants such as number of ALE ports, stats modules and number of ports are defined through constants. These are now changed to variables in gbe_priv data that get set based on the compatibility string. This is required as there are no hardware identification registers available to distinguish among the variants of NetCP 1.5 ethss. However there is identification register available to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use of in the code to differentiate them.

2015-03-20net: netcp: use separate reg region for individual ethss modulesKaricheri, Muralidharan
Ethss has multiple modules within the sub system - switch sub system - sgmii - mdio - switch module NetCP driver re-uses existing davinci mdio driver. It requires to have its own register region to map the reg space. So restructure the code to use separate reg region for the individual modules it manages. Use range property to define register space of NetCP and use reg property to define individual reg spaces. So MDIO will have its own reg space to map. This is a pre-requisite to enable MDIO driver for NetCP. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: WingMan Kwok <w-kwok2@ti.com> CC: "David S.

Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>

2015-03-18cc2520: Add support for CC2591 amplifier.Brad Campbell
The TI CC2521 is an RF power amplifier that is designed to interface with the CC2520. Conveniently, it directly interfaces with the CC2520 and does not require any pins to be connected to a microcontroller/processor. Adding a CC2591 increases the CC2520's range, which is useful for border router and other wall-powered applications. Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs that are connected to the CC2591 to correctly set the CC2591 into TX and RX modes. Further, TI recommends that the CC2520_TXPOWER and CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's performance. These settings are covered in TI Application Note AN065. This patch adds an optional `amplified` field to the cc2520 entry in the device tree. If present, the CC2520 will be configured to operate with a CC2591. The expected pin mapping is: CC2520 GPIO0 --> CC2591 EN CC2520 GPIO5 --> CC2591 PAEN Signed-off-by: Brad Campbell <bradjc5@gmail.com> Acked-by: Varka Bhadram <varkabhadram@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Allows one to force Data Carrier Detect, Clear To Send, and Data Set Ready signals to permanently be reported as active. The Ring indicator can be forced to be reported as inactive. It is possible that if modem control signalling is enabled on a port that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the driver can hang indefinitely waiting for the state to change. The new DT properties allow the driver to ignore the state of these pins on serial ports that don't support them, as recommended in the kernel documentation.

Specifics: - Fix ACPI resources management problems introduced by the recent rework of the code in question (Jiang Liu) and a build issue introduced by those changes (Joachim Nilsson). - Fix a recent suspend-to-idle regression on systems where entering idle states causes local timers to stop, prevent suspend-to-idle from crashing in restricted configurations (no cpuidle driver, cpuidle disabled etc.) and clean up the idle loop somewhat while at it (Rafael J Wysocki). - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven). - Allow the ACPI backlight driver module to be loaded if ACPI is disabled which helps the i915 driver in those configurations (stable-candidate) and change the code to help debug unusual use cases (Chris Wilson). - Wakeup IRQ management changes in v3.18 caused some drivers on the at91 platform to trigger a warning from the IRQ core related to an unexpected combination of interrupt action handler flags. However, on at91 a timer IRQ is shared with some other devices (including system wakeup ones) and that leads to the unusual combination of flags in question. To make it possible to avoid the warning introduce a new interrupt action handler flag (which can be used by drivers to indicate the special case to the core) and rework the problematic at91 drivers to use it and work as expected during system suspend/resume.

2015-03-06genirq / PM: describe IRQF_COND_SUSPENDMark Rutland
With certain restrictions it is possible for a wakeup device to share an IRQ with an IRQF_NO_SUSPEND user, and the warnings introduced by commit cab303be91dc47942bc25de33dc1140123540800 are spurious. The new IRQF_COND_SUSPEND flag allows drivers to tell the core when these restrictions are met, allowing spurious warnings to be silenced. This patch documents how IRQF_COND_SUSPEND is expected to be used, updating some of the text now made invalid by its addition.

2015-03-04mpls: Add a sysctl to control the size of the mpls label tableEric W. Biederman
This sysctl gives two benefits. By defaulting the table size to 0 mpls even when compiled in and enabled defaults to not forwarding any packets. This prevents unpleasant surprises for users. The other benefit is that as mpls labels are allocated locally a dense table a small dense label table may be used which saves memory and is extremely simple and efficient to implement. This sysctl allows userspace to choose the restrictions on the label table size userspace applications need to cope with. Signed-off-by: "Eric W.

2015-02-26genirq / PM: better describe IRQF_NO_SUSPEND semanticsMark Rutland
The IRQF_NO_SUSPEND flag is intended to be used for interrupts required to be enabled during the suspend-resume cycle. This mostly consists of IPIs and timer interrupts, potentially including chained irqchip interrupts if these are necessary to handle timers or IPIs. If an interrupt does not fall into one of the aforementioned categories, requesting it with IRQF_NO_SUSPEND is likely incorrect. Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the system from a suspended state. For an interrupt to be able to trigger a wakeup, it may be necessary to program various components of the system. In these cases it is necessary to use {enable,disabled}_irq_wake. Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that an IRQ can wake up the system, and the documentation can be read ambiguously w.r.t. this property. This patch updates the documentation regarding IRQF_NO_SUSPEND to make this caveat explicit, hopefully making future misuse rarer. Cleanup of existing misuse will occur as part of later patch series.
