git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "This series contains HCH's changes to absorb configfs attribute ->show() + ->store() function pointer usage from it's original tree-wide consumers, into common configfs code. It includes usb-gadget, target w/ drivers, netconsole and ocfs2 changes to realize the improved simplicity, that now renders the original include/target/configfs_macros.h CPP magic for fabric drivers and others, unnecessary and obsolete. And with common code in place, new configfs attributes can be added easier than ever before. Note, there are further improvements in-flight from other folks for v4.5 code in configfs land, plus number of target fixes for post -rc1 code" In the meantime, a new user of the now-removed old configfs API came in through the char/misc tree in commit 7bd1d4093c2f ("stm class: Introduce an abstraction for System Trace Module devices"). This merge resolution comes from Alexander Shishkin, who updated his stm class tracing abstraction to account for the removal of the old show_attribute and store_attribute methods in commit 517982229f78 ("configfs: remove old API") from this pull. As Alexander says about that patch: "There's no need to keep an extra wrapper structure per item and the awkward show_attribute/store_attribute item ops are no longer needed. This patch converts policy code to the new api, all the while making the code quite a bit smaller and easier on the eyes. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>" That patch was folded into the merge so that the tree should be fully bisectable. * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (23 commits) configfs: remove old API ocfs2/cluster: use per-attribute show and store methods ocfs2/cluster: move locking into attribute store methods netconsole: use per-attribute show and store methods target: use per-attribute show and store methods spear13xx_pcie_gadget: use per-attribute show and store methods dlm: use per-attribute show and store methods usb-gadget/f_serial: use per-attribute show and store methods usb-gadget/f_phonet: use per-attribute show and store methods usb-gadget/f_obex: use per-attribute show and store methods usb-gadget/f_uac2: use per-attribute show and store methods usb-gadget/f_uac1: use per-attribute show and store methods usb-gadget/f_mass_storage: use per-attribute show and store methods usb-gadget/f_sourcesink: use per-attribute show and store methods usb-gadget/f_printer: use per-attribute show and store methods usb-gadget/f_midi: use per-attribute show and store methods usb-gadget/f_loopback: use per-attribute show and store methods usb-gadget/ether: use per-attribute show and store methods usb-gadget/f_acm: use per-attribute show and store methods usb-gadget/f_hid: use per-attribute show and store methods ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more power management and ACPI updates from Rafael Wysocki: "The only new feature in this batch is support for the ACPI _CCA device configuration object, which it a pre-requisite for future ACPI PCI support on ARM64, but should not affect the other architectures. The rest is fixes and cleanups, mostly in cpufreq (including intel_pstate), the Operating Performace Points (OPP) framework and tools (cpupower and turbostat). Specifics: - Support for the ACPI _CCA configuration object intended to tell the OS whether or not a bus master device supports hardware managed cache coherency and a new set of functions to allow drivers to check the cache coherency support for devices in a platform firmware interface agnostic way (Suravee Suthikulpanit, Jeremy Linton). - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X (Aaron Lu, Hans de Goede). - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers (Jon Medhurst, Nicolas Pitre). - kfree()-related fixup for the recently introduced CPPC cpufreq frontend (Markus Elfring). - intel_pstate fix reducing kernel log noise on systems where P-states are managed by hardware (Prarit Bhargava). - intel_pstate maintainers information update (Srinivas Pandruvada). - cpufreq core optimization related to the handling of delayed work items used by governors (Viresh Kumar). - Locking fixes and cleanups of the Operating Performance Points (OPP) framework (Viresh Kumar). - Generic power domains framework cleanups (Lina Iyer). - cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan, Thomas Renninger). - turbostat tool updates (Len Brown)" * tag 'pm+acpi-4.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) PCI: ACPI: Add support for PCI device DMA coherency PCI: OF: Move of_pci_dma_configure() to pci_dma_configure() of/pci: Fix pci_get_host_bridge_device leak device property: ACPI: Remove unused DMA APIs device property: ACPI: Make use of the new DMA Attribute APIs device property: Adding DMA Attribute APIs for Generic Devices ACPI: Adding DMA Attribute APIs for ACPI Device device property: Introducing enum dev_dma_attr ACPI: Honor ACPI _CCA attribute setting cpufreq: CPPC: Delete an unnecessary check before the function call kfree() PM / OPP: Add opp_rcu_lockdep_assert() to _find_device_opp() PM / OPP: Hold dev_opp_list_lock for writers PM / OPP: Protect updates to list_dev with mutex PM / OPP: Propagate error properly from dev_pm_opp_set_sharing_cpus() cpufreq: s5pv210-cpufreq: fix wrong do_div() usage MAINTAINERS: update for intel P-state driver Creating a common structure initialization pattern for struct option cpupower: Enable disabled Cstates if they are below max latency cpupower: Remove debug message when using cpupower idle-set -D switch cpupower: cpupower monitor reports uninitialized values for offline cpus ...

2015-11-11pcnet32: use pci_set_dma_mask insted of pci_dma_supportedChristoph Hellwig
All drivers should be using dma_set_mask / pci_set_dma_mask to try to set the dma mask instead of just querying it. Without that some iommu implementations may not work. pci_dma_supported is removed entirely, but dma_supported stays for dma_ops implementations for now. This patch (of 15): This ensures the dma mask that is supported by the driver is recorded in the device structure.

2015-11-10net: mvneta: Fix memory use after free.Justin Maggard
After changing an interface's MTU, then bringing the interface down and back up again, I immediately saw tons of kernel messages like below. The reason for this bad behavior is mvneta_rxq_drop_pkts(), which calls dma_unmap_single() on already-freed memory. So we need to switch the order of those two operations.

2015-11-09mvneta: add FIXED_PHY dependencyArnd Bergmann
The fixed_phy infrastructure is done in a way that is optional, by providing 'static inline' helper functions doing nothing in include/linux/phy_fixed.h for all its APIs. However, three out of the four users (DSA, BCMGENET, and SYSTEMPORT) always 'select FIXED_PHY', presumably because they need that. MVNETA is the fourth one, and if that is built-in but FIXED_PHY is configured as a loadable module, we get a link error: drivers/built-in.o: In function `mvneta_fixed_link_update': fpga-mgr.c:(.text+0x33ed80): undefined reference to `fixed_phy_update_state' Presumably this driver has the same dependency as the others, so this patch also uses 'select' to ensure that the fixed-phy support is built-in.

2015-11-07bonding: fix panic on non-ARPHRD_ETHER enslave failureJay Vosburgh
Since commit 7d5cd2ce529b, when bond_enslave fails on devices that are not ARPHRD_ETHER, if needed, it resets the bonding device back to ARPHRD_ETHER by calling ether_setup. Unfortunately, ether_setup clobbers dev->flags, clearing IFF_UP if the bond device is up, leaving it in a quasi-down state without having actually gone through dev_close. For bonding, if any periodic work queue items are active (miimon, arp_interval, etc), those will remain running, as they are stopped by bond_close. At this point, if the bonding module is unloaded or the bond is deleted, the system will panic when the work function is called. This panic is resolved by calling dev_close on the bond itself prior to calling ether_setup.

2015-11-07net/qlcnic: fix mac address restore in bond mode 5/6Jarod Wilson
The bonding driver saves a copy of slaves' original mac address and then assigns whatever mac as needed to the slave, depending on mode. In at least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the mac address of another slave. On release from the bond, the original mac address is supposed to get restored via a dev_set_mac_address() call in the bonding driver's __bond_release_one() function, which calls the slave's ndo_set_mac_address function, which for qlcnic, is qlcnic_set_mac(). Now, this function tries to be somewhat intelligent and exit early if you're trying to set the mac address to the same thing that is already set. The problem here is that adapter->mac_addr isn't in sync with netdev->dev_addr. The qlcnic driver still has the original mac stored in adapter->mac_addr, while the bonding driver has updated netdev->dev_addr, so qlcnic thinks we're trying to set the same address it already has. I think the way to go here, since the function updates both netdev and adapter's stored mac addresses, is to check if either of them doesn't match the newly requested mac. Simply checking netdev's value only could result in a similar mismatch and non-update, so look at both.

2015-11-07mm, page_alloc: distinguish between being unable to sleep, unwilling to ↵Mel Gorman
sleep and avoiding waking kswapd __GFP_WAIT has been used to identify atomic context in callers that hold spinlocks or are in interrupts. They are expected to be high priority and have access one of two watermarks lower than "min" which can be referred to as the "atomic reserve". __GFP_HIGH users get access to the first lower watermark and can be called the "high priority reserve". Over time, callers had a requirement to not block when fallback options were available. Some have abused __GFP_WAIT leading to a situation where an optimisitic allocation with a fallback option can access atomic reserves. This patch uses __GFP_ATOMIC to identify callers that are truely atomic, cannot sleep and have no alternative. High priority users continue to use __GFP_HIGH. __GFP_DIRECT_RECLAIM identifies callers that can sleep and are willing to enter direct reclaim. __GFP_KSWAPD_RECLAIM to identify callers that want to wake kswapd for background reclaim. __GFP_WAIT is redefined as a caller that is willing to enter direct reclaim and wake kswapd for background reclaim. This patch then converts a number of sites o __GFP_ATOMIC is used by callers that are high priority and have memory pools for those requests. GFP_ATOMIC uses this flag. o Callers that have a limited mempool to guarantee forward progress clear __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall into this category where kswapd will still be woken but atomic reserves are not used as there is a one-entry mempool to guarantee progress. o Callers that are checking if they are non-blocking should use the helper gfpflags_allow_blocking() where possible. This is because checking for __GFP_WAIT as was done historically now can trigger false positives. Some exceptions like dm-crypt.c exist where the code intent is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to flag manipulations. o Callers that built their own GFP flags instead of starting with GFP_KERNEL and friends now also need to specify __GFP_KSWAPD_RECLAIM. The first key hazard to watch out for is callers that removed __GFP_WAIT and was depending on access to atomic reserves for inconspicuous reasons. In some cases it may be appropriate for them to use __GFP_HIGH. The second key hazard is callers that assembled their own combination of GFP flags instead of starting with something like GFP_KERNEL. They may now wish to specify __GFP_KSWAPD_RECLAIM. It's almost certainly harmless if it's missed in most cases as other activity will wake kswapd.

The DSA documentation specifies that each port must be capable of forwarding frames to the CPU port. The last changes on bridging support for the mv88e6xxx driver broke this requirement for non-bridged ports. So as for the bridged ports, reserve a few VLANs (4000+) in the switch to isolate ports that have not been bridged yet. By default, a port will be isolated with the CPU and DSA ports. When the port joins a bridge, it will leave its reserved port. When it is removed from a bridge, it will join its reserved VLAN again.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking changes from Ingo Molnar: "The main changes in this cycle were: - More gradual enhancements to atomic ops: new atomic*_read_ctrl() ops, synchronize atomic_{read,set}() ordering requirements between architectures, add atomic_long_t bitops. (Peter Zijlstra) - Add _{relaxed|acquire|release}() variants for inc/dec atomics and use them in various locking primitives: mutex, rtmutex, mcs, rwsem. This enables weakly ordered architectures (such as arm64) to make use of more locking related optimizations. (Davidlohr Bueso) - Implement atomic[64]_{inc,dec}_relaxed() on ARM. (Will Deacon) - Futex kernel data cache footprint micro-optimization. (Rasmus Villemoes) - pvqspinlock runtime overhead micro-optimization.

Commit 7d7355f58ba4 ("sh_eth: Ensure proper ordering of descriptor active bit write/read") did the right thing but used too "heavy" barriers while there were already "lighter" DMA barriers exactly for this case...
