2014-08-15net: xilinx: Remove .owner field for driverMichal Simek3-3/+0
There is no need to init .owner field. Based on the patch from Peter Griffin <peter.griffin@linaro.org> "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-08-12 This series contains updates to i40e and e1000e. Lucas provides a fix for i40e to resolve a compile issue where a header was missing in the #includes. Wei Yongjun provides a fix for i40e to resolve a sparse warning, where a non-static function should be static. Julia Lawall provides a fix for i40e which was found using Coccinelle, where there was a typo in the name of the type given to sizeof(). Rickard Strandqvist provides a fix for i40e to replace the use of strncpy() with strlcpy() to avoid strings that lack null termination. Jean Sacren provides two e1000e fixes, first is a comment fix and second removes an excessive space character in a debug message. ==================== Signed-off-by: David S.

The sender could have sent us a burst, and gone to lunch without doing any more ldc_read()'s. That should not cause the receiver to loop infinitely till soft-lockup kicks in. Similarly __vnet_tx_trigger should only loop on EAGAIN a finite number of times.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86/apic updates from Thomas Gleixner: "This is a major overhaul to the x86 apic subsystem consisting of the following parts: - Remove obsolete APIC driver abstractions (David Rientjes) - Use the irqdomain facilities to dynamically allocate IRQs for IOAPICs. This is a prerequisite to enable IOAPIC hotplug support, and it also frees up wasted vectors (Jiang Liu) - Misc fixlets. Despite the hickup in Ingos previous pull request - caused by the missing fixup for the suspend/resume issue reported by Borislav - I strongly recommend that this update finds its way into 3.17. Some history for you: This is preparatory work for physical IOAPIC hotplug. The first attempt to support this was done by Yinghai and I shot it down because it just added another layer of obscurity and complexity to the already existing mess without tackling the underlying shortcomings of the current implementation. After quite some on- and offlist discussions, I requested that the design of this functionality must use generic infrastructure, i.e. irq domains, which provide all the mechanisms to dynamically map linux interrupt numbers to physical interrupts. Jiang picked up the idea and did a great job of consolidating the existing interfaces to manage the x86 (IOAPIC) interrupt system by utilizing irq domains. The testing in tip, Linux-next and inside of Intel on various machines did not unearth any oddities until Borislav exposed it to one of his oddball machines. The issue was resolved quickly, but unfortunately the fix fell through the cracks and did not hit the tip tree before Ingo sent the pull request. Not entirely Ingos fault, I also assumed that the fix was already merged when Ingo asked me whether he could send it. Nevertheless this work has a proper design, has undergone several rounds of review and the final fallout after applying it to tip and integrating it into Linux-next has been more than moderate. It's the ground work not only for IOAPIC hotplug, it will also allow us to move the lowlevel vector allocation into the irqdomain hierarchy, which will benefit other architectures as well. Patches are posted already, but they are on hold for two weeks, see below. I really appreciate the competence and responsiveness Jiang has shown in course of this endavour. So I'm sure that any fallout of this will be addressed in a timely manner. FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA will have a look at the hopefully zero fallout until I'm back" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) x86, irq, PCI: Keep IRQ assignment for PCI devices during suspend/hibernation x86/apic/vsmp: Make is_vsmp_box() static x86, apic: Remove enable_apic_mode callback x86, apic: Remove setup_portio_remap callback x86, apic: Remove multi_timer_check callback x86, apic: Replace noop_check_apicid_used x86, apic: Remove check_apicid_present callback x86, apic: Remove mps_oem_check callback x86, apic: Remove smp_callin_clear_local_apic callback x86, apic: Replace trampoline physical addresses with defaults x86, apic: Remove x86_32_numa_cpu_node callback x86: intel-mid: Use the new io_apic interfaces x86, vsmp: Remove is_vsmp_box() from apic_is_clustered_box() x86, irq: Clean up irqdomain transition code x86, irq, devicetree: Release IOAPIC pin when PCI device is disabled x86, irq, SFI: Release IOAPIC pin when PCI device is disabled x86, irq, mpparse: Release IOAPIC pin when PCI device is disabled x86, irq, ACPI: Release IOAPIC pin when PCI device is disabled x86, irq: Introduce helper functions to release IOAPIC pin x86, irq: Simplify the way to handle ISA IRQ ...

2014-08-12net: bcmgenet: correctly resume adapter from Wake-on-LANFlorian Fainelli1-4/+6
In case we configured the adapter to be a wake up source from Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will leave the adapter in MagicPacket matching mode, which prevents any other type of packets from reaching the RX engine. Fix this by calling bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter configuration in bcmgenet_resume(). The second problem we had was an imbalanced clock disabling in bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally disabled the clock in bcmgenet_wol_resume().

2014-08-12net: bcmgenet: update UMAC_CMD only when link is detectedFlorian Fainelli1-2/+6
When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the GENET hardware block, and this will cause bus errors to happen in bcmgenet_mii_setup(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case Fixes: 240524089d7a ("net: bcmgenet: only update UMAC_CMD if something changed") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

We had two calls to bcmgenet_mii_reset() which will issue a software-reset to the PHY without using the PHY library, get rid of them since they are completely bogus and mess up with the PHY library state. Make sure that we reset the PHY library cached values (link, pause and duplex) to allow the link adjustment callback to be invoked when needed.

2014-08-12net: bcmgenet: request and enable main clock earlierFlorian Fainelli1-7/+7
bcmgenet_set_hw_params() will read the hardware version and compare it with the one we are getting from Device Tree. Due to the clock being enabled too late, bcmgenet_set_hw_params() will cause bus errors since the GENET hardware block is still gated off by the time bcmgenet_set_hw_params() is called, this will also make us fail the version check since we will read the value 0 from the hardware. Fix this by requesting the clock before the first piece of code that needs to access hardware register.

2014-08-12xen-netfront: Fix handling packets on compound pages with skb_linearizeZoltan Kiss1-3/+4
There is a long known problem with the netfront/netback interface: if the guest tries to send a packet which constitues more than MAX_SKB_FRAGS + 1 ring slots, it gets dropped. The reason is that netback maps these slots to a frag in the frags array, which is limited by size. Having so many slots can occur since compound pages were introduced, as the ring protocol slice them up into individual (non-compound) page aligned slots. The theoretical worst case scenario looks like this (note, skbs are limited to 64 Kb here): linear buffer: at most PAGE_SIZE - 17 * 2 bytes, overlapping page boundary, using 2 slots first 15 frags: 1 + PAGE_SIZE + 1 bytes long, first and last bytes are at the end and the beginning of a page, therefore they use 3 * 15 = 45 slots last 2 frags: 1 + 1 bytes, overlapping page boundary, 2 * 2 = 4 slots Although I don't think this 51 slots skb can really happen, we need a solution which can deal with every scenario. In real life there is only a few slots overdue, but usually it causes the TCP stream to be blocked, as the retry will most likely have the same buffer layout. This patch solves this problem by linearizing the packet. This is not the fastest way, and it can fail much easier as it tries to allocate a big linear area for the whole packet, but probably easier by an order of magnitude than anything else. Probably this code path is not touched very frequently anyway.
