2014-11-21dt/bindings: add clock-select function property to micrel phy bindingJohan Hovold
Add "micrel,rmii-reference-clock-select-25-mhz" to Micrel ethernet PHY binding documentation. This property is needed to properly describe some revisions of Micrel PHYs which has the function of this configuration bit inverted so that setting it enables 25 MHz rather than 50 MHz clock mode. Note that a clock reference ("rmii-ref") is still needed to actually select either mode.

2014-11-21net: phy: micrel: add support for clock-mode select to KSZ8081/KSZ8091Johan Hovold
Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select bit, which is used to select 25 or 50 MHz clock mode. Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of this bit is inverted so that setting it enables 25 rather than 50 MHz mode. Add a new device-tree property "micrel,rmii-reference-clock-select-25-mhz" to describe this. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Some TI SoCs like DRA7 have a RAMINIT register specification different from the other AMxx SoCs and as expected by the existing driver. To add more insanity, this register is shared with other IPs like DSS, PCIe and PWM. Provides a more generic mechanism to specify the RAMINIT register location and START/DONE bit position and use the syscon/regmap framework to access the register.

2014-11-16net: provide a per host RSS key generic infrastructureEric Dumazet
RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes RSS key. Some drivers use a constant (and well known key), some drivers use a random key per port, making bonding setups hard to tune. Well known keys increase attack surface, considering that number of queues is usually a power of two. This patch provides infrastructure to help drivers doing the right thing. netdev_rss_key_fill() should be used by drivers to initialize their RSS key, even if they provide ethtool -X support to let user redefine the key later. A new /proc/sys/net/core/netdev_rss_key file can be used to get the host RSS key even for drivers not providing ethtool -x support, in case some applications want to precisely setup flows to match some RX queues. Tested: myhost:~# cat /proc/sys/net/core/netdev_rss_key 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41:36:40:74:b6:15:ca:27:44:aa:b3:4d:72 myhost:~# ethtool -x eth0 RX flow hash indirection table for eth0 with 8 RX ring(s): 0: 0 1 2 3 4 5 6 7 RSS hash key: 11:63:99:bb:79:fb:a5:a7:07:45:b2:20:bf:02:42:2d:08:1a:dd:19:2b:6b:23:ac:56:28:9d:70:c3:ac:e8:16:4b:b7:c1:10:53:a4:78:41 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2014-11-11net: Convert LIMIT_NETDEBUG to net_dbg_ratelimitedJoe Perches
Use the more common dynamic_debug capable net_dbg_ratelimited and remove the LIMIT_NETDEBUG macro. All messages are still ratelimited. Some KERN_<LEVEL> uses are changed to KERN_DEBUG. This may have some negative impact on messages that were emitted at KERN_INFO that are not not enabled at all unless DEBUG is defined or dynamic_debug is enabled. Even so, these messages are now _not_ emitted by default. This also eliminates the use of the net_msg_warn sysctl "/proc/sys/net/core/warnings". For backward compatibility, the sysctl is not removed, but it has no function. The extern declaration of net_msg_warn is removed from sock.h and made static in net/core/sysctl_net_core.c Miscellanea: o Update the sysctl documentation o Remove the embedded uses of pr_fmt o Coalesce format fragments o Realign arguments Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

With legacy booting, the platform init code was taking care of the configuring of GPIOs. With device tree based booting, things may or may not work depending what bootloader has configured or if the legacy platform code gets called. Let's add support for the pwrdn and reset GPIOs to the smc91x driver to fix the issues of smc91x not working properly when booted in device tree mode. And let's change n900 to use these settings as some versions of the bootloader do not configure things properly causing errors.

2014-10-29net: ipv6: Add a sysctl to make optimistic addresses useful candidatesErik Kline
Add a sysctl that causes an interface's optimistic addresses to be considered equivalent to other non-deprecated addresses for source address selection purposes. Preferred addresses will still take precedence over optimistic addresses, subject to other ranking in the source address selection algorithm. This is useful where different interfaces are connected to different networks from different ISPs (e.g., a cell network and a home wifi network). The current behaviour complies with RFC 3484/6724, and it makes sense if the host has only one interface, or has multiple interfaces on the same network (same or cooperating administrative domain(s), but not in the multiple distinct networks case. For example, if a mobile device has an IPv6 address on an LTE network and then connects to IPv6-enabled wifi, while the wifi IPv6 address is undergoing DAD, IPv6 connections will try use the wifi default route with the LTE IPv6 address, and will get stuck until they time out. Also, because optimistic nodes can receive frames, issue an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC flag appropriately set). A second RTM_NEWADDR is sent if DAD completes (the address flags have changed), otherwise an RTM_DELADDR is sent. Also: add an entry in ip-sysctl.txt for optimistic_dad.

2014-10-29tcp: allow for bigger reordering levelEric Dumazet
While testing upcoming Yaogong patch (converting out of order queue into an RB tree), I hit the max reordering level of linux TCP stack. Reordering level was limited to 127 for no good reason, and some network setups [1] can easily reach this limit and get limited throughput. Allow a new max limit of 300, and add a sysctl to allow admins to even allow bigger (or lower) values if needed.

This patch brings back the makefile called testptp.mk which was removed in commit adb19fb66eee (Documentation: add makefiles for more targets). While the idea of that commit was to improve build coverage of the examples, the new Makefile is unable to cross compile the testptp program. In contrast, the deleted makefile was able to do this just fine. This patch fixes the regression by restoring the original makefile.

The only really new thing here is the PM QoS class for memory bandwidth, but it is simple enough and users of it will be added in the next cycle. One major change in behavior is that platform devices enumerated by ACPI will use 32-bit DMA mask by default. Also included is an ACPICA update to a new upstream release, but that's mostly cleanups, changes in tools and similar. The rest is fixes and cleanups mostly. Specifics: - Fix for a recent PCI power management change that overlooked the fact that some IRQ chips might not be able to configure PCIe PME for system wakeup from Lucas Stach. - Fix for a bug introduced in 3.17 where acpi_device_wakeup() is called with a wrong ordering of arguments from Zhang Rui. - A bunch of intel_pstate driver fixes (all -stable candidates) from Dirk Brandewie, Gabriele Mazzotta and Pali Rohár. - Fixes for a rather long-standing problem with the OOM killer and the freezer that frozen processes killed by the OOM do not actually release any memory until they are thawed, so OOM-killing them is rather pointless, with a couple of cleanups on top (Michal Hocko, Cong Wang, Rafael J Wysocki). - ACPICA update to upstream release 20140926, inlcuding mostly cleanups reducing differences between the upstream ACPICA and the kernel code, tools changes (acpidump, acpiexec) and support for the _DDN object (Bob Moore, Lv Zheng). - New PM QoS class for memory bandwidth from Tomeu Vizoso. - Default 32-bit DMA mask for platform devices enumerated by ACPI (this change is mostly needed for some drivers development in progress targeted at 3.19) from Heikki Krogerus. - ACPI EC driver cleanups, mostly related to debugging, from Lv Zheng. - cpufreq-dt driver updates from Thomas Petazzoni. - powernv cpuidle driver update from Preeti U Murthy" * tag 'pm+acpi-3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (34 commits) intel_pstate: Correct BYT VID values. intel_pstate: Fix BYT frequency reporting intel_pstate: Don't lose sysfs settings during cpu offline cpufreq: intel_pstate: Reflect current no_turbo state correctly cpufreq: expose scaling_cur_freq sysfs file for set_policy() drivers cpufreq: intel_pstate: Fix setting max_perf_pct in performance policy PCI / PM: handle failure to enable wakeup on PCIe PME ACPI: invoke acpi_device_wakeup() with correct parameters PM / freezer: Clean up code after recent fixes PM: convert do_each_thread to for_each_process_thread OOM, PM: OOM killed task shouldn't escape PM suspend freezer: remove obsolete comments in __thaw_task() freezer: Do not freeze tasks killed by OOM killer ACPI / platform: provide default DMA mask cpuidle: powernv: Populate cpuidle state details by querying the device-tree cpufreq: cpufreq-dt: adjust message related to regulators cpufreq: cpufreq-dt: extend with platform_data cpufreq: allow driver-specific data ACPI / EC: Cleanup coding style.

Now the buggy patch has been dropped entirely from my next branch. Thus I hope those changes can still be merged in 3.18-rc2 as most of them are platform thermal driver changes. Specifics: - introduce ACPI INT340X thermal drivers. Newer laptops and tablets may have thermal sensors and other devices with thermal control capabilities that are exposed for the OS to use via the ACPI INT340x device objects. Several drivers are introduced to expose the temperature information and cooling ability from these objects to user-space via the normal thermal framework. From: Lu Aaron, Lan Tianyu, Jacob Pan and Zhang Rui. - introduce a new thermal governor, which just uses a hysteresis to switch abruptly on/off a cooling device. This governor can be used to control certain fan devices that can not be throttled but just switched on or off.
