2016-05-11dsa: Move gpio reset into switch driverAndrew Lunn
Resetting the switch is something the driver does, not the framework. So move the parsing of this property into the driver. There are no in kernel users of this property, so moving it does not break anything. There is however a board which will make use of this property making its way into the kernel.

2016-05-11dsa: Add mdio device support to Marvell switchesAndrew Lunn
Allow Marvell switches to be mdio devices. Currently the driver just allocate the private structure and detects what device is on the bus. Later patches will make them register with the DSA framework. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-11dsa: mv88e6xxx: Rename probe function to fit the normal patternAndrew Lunn

2016-05-11net: dsa: mv88e6xxx: add STU capabilityVivien Didelot
Some switch models have a STU (per VLAN port state database). Add a new capability flag to switches info, instead of checking their family. Also if the 6165 family has an STU, it must have a VTU, so add the MV88E6XXX_FLAG_VTU to its family flags.

2016-05-11net: l3mdev: Add hook in ip and ipv6David Ahern
Currently the VRF driver uses the rx_handler to switch the skb device to the VRF device. Switching the dev prior to the ip / ipv6 layer means the VRF driver has to duplicate IP/IPv6 processing which adds overhead and makes features such as retaining the ingress device index more complicated than necessary. This patch moves the hook to the L3 layer just after the first NF_HOOK for PRE_ROUTING. This location makes exposing the original ingress device trivial (next patch) and allows adding other NF_HOOKs to the VRF driver in the future. dev_queue_xmit_nit is exported so that the VRF driver can cycle the skb with the switched device through the packet taps to maintain current behavior (tcpdump can be used on either the vrf device or the enslaved devices).

2016-05-11PCI: Provide common functions for ECAM mappingJayachandran C
Add config option PCI_ECAM and file drivers/pci/ecam.c to provide generic functions for accessing memory-mapped PCI config space. The API is defined in drivers/pci/ecam.h and is written to replace the API in drivers/pci/host/pci-host-common.h. The file defines a new 'struct pci_config_window' to hold the information related to a PCI config area and its mapping. This structure is expected to be used as sysdata for controllers that have ECAM based mapping. Helper functions are provided to setup the mapping, free the mapping and to implement the map_bus method in 'struct pci_ops' Signed-off-by: Jayachandran C <jchandra@broadcom.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-05-11intel_pstate: Clean up get_target_pstate_use_performance()Rafael J. Wysocki
The comments and the core_busy variable name in get_target_pstate_use_performance() are totally confusing, so modify them to reflect what's going on. The results of the computations should be the same as before. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2016-05-11intel_pstate: Use sample.core_avg_perf in get_avg_pstate()Rafael J. Wysocki
Notice that get_avg_pstate() can use sample.core_avg_perf instead of carrying the same division again, so make it do that. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2016-05-11intel_pstate: Clarify average performance computationRafael J. Wysocki
The core_pct_busy field of struct sample actually contains the average performace during the last sampling period (in percent) and not the utilization of the core as suggested by its name which is confusing. For this reason, change the name of that field to core_avg_perf and rename the function that computes its value accordingly. Also notice that storing this value as percentage requires a costly integer multiplication to be carried out in a hot path, so instead store it as an "extended fixed point" value with more fraction bits and update the code using it accordingly (it is better to change the name of the field along with its meaning in one go than to make those two changes separately, as that would likely lead to more confusion).

2016-05-11intel_pstate: Avoid unnecessary synchronize_sched() during initializationChen Yu
Currently, in intel_pstate_clear_update_util_hook(), after clearing the utilization update hook, we leverage synchronize_sched() to deal with synchronization, which is a little bit time-costly because synchronize_sched() has to wait for all the CPUs to go through a grace period. Actually, the synchronize_sched() is not necessary if the utilization update hook has not been set for the given CPU yet, so make the driver check if that's the case and avoid the synchronize_sched() call then.

Adds 16K page size support based on the above. Adds a generic firmware probing layer for the timer and GIC so that KVM initializes using the same logic based on both ACPI and FDT. Finally adds support for hardware updating of the access flag.

2016-05-11platform/chrome: cros_ec_lightbar - use name instead of ID to hide lightbar ↵Clinton Sprain
attributes Lightbar attributes are hidden if the ID of the device is not 0 (the assumption being that 0 = cros_ec = might have a lightbar, 1 = cros_pd = hide); however, sometimes these devices get IDs 1 and 2 (or something else) instead of IDs 0 and 1. This prevents the lightbar attributes from appearing when they should. Proposed change is to instead check whether the name assigned to the device is CROS_EC_DEV_NAME (true for cros_ec, false for cros_pd).

2016-05-11platform/chrome: cros_ec_dev - Fix security issueGwendal Grignou
Prevent memory scribble by checking that ioctl buffer size parameters are sane. Without this check, on 32 bits system, if .insize = 0xffffffff - 20 and .outsize the amount to scribble, we would overflow, allocate a small amounts and be able to write outside of the malloc'ed area. Adding a hard limit allows argument checking of the ioctl. With the current EC, it is expected .insize and .outsize to be at around 512 bytes or less.

What about if "rtlphy->pwrgroup_cnt" is 2? In that case we would use an uninitialized "chnlgroup" variable and probably crash. Maybe that can't happen for some reason which is not obvious but in that case this patch is harmless. Setting it to zero seems like a standard default in the surrounding code so it's probably fine here as well.
