Since commit 3d7608e4 ("ARM: shmobile: bockw: remove legacy board file and config"), R-Car Gen1 SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Protect sh_eth_set_rate_r8a777x() and r8a777x_data by #ifdef CONFIG_OF, as they're now referenced on DT platforms only. Signed-off-by:

Since commit 1fa59bda ("ARM: shmobile: Remove legacy board code for Armadillo-800 EVA"), r8a7740 is only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Protect r8a7740_data by #ifdef CONFIG_OF as it's now referenced on DT platforms only. Move it to a more logical position, in front of the r8a777x support, so we can have a single #ifdef covering all r7s* and r8a* support soon. This requires moving a few helper functions, too.

The private slave queue and slave struct haven't been used for anything and aren't needed, this allows to reduce memory usage and simplify enslave/release. We can use netdev_for_each_lower_dev() to free the vrf ports when deleting a vrf device. Also if in the future a private struct is needed for each slave, it can be implemented via lower devices' private member (similar to how bonding does it). Signed-off-by:

Commit 09605cc1 ("net ipv4: use preferred log methods") replaced a few calls of pr_cont() after a console print without a trailing newline by pr_info(), causing lines to be split during IP autoconfiguration, like: . , OK IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44 Convert these back to using pr_cont(), so it prints again: ., OK IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44 Absorb the printing of "my address ..." into the previous call to pr_info(), as there's no reason to use a continuation there. Convert one more pr_info() to print nameservers while we're at it. Fixes: 09605cc1 ("net ipv4: use preferred log methods") Signed-off-by:

After the introduction of the switch gpio reset API, I'm getting build errors in configurations that disable CONFIG_GPIOLIB: net/dsa/dsa.c:783:16: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration] The reason is that linux/gpio/consumer.h is not automatically included without gpiolib support. This adds an explicit #include statement to make it compile in all configurations. The reset functionality will not work without gpiolib, which is what you get when disabling the feature. As far as I can tell, gpiolib is supported on all architectures on which you can have DSA at the moment. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-11-23 This series contains updates to ixgbe, ixgbevf, fm10k, i40e and i40evf. Jacob fixes an issue where VF could attempt to read queues it does not own, so prevent this we check queue 0 before we continue. Matthew fixes the MTU for jumbo frames for fm10k. Julia Lawall cleans up a unneeded NULL test in ixgbe. Mark cleans up a redundant header inclusion. Adds KR mode support for CS4227 chip. Cleaned up diagnostic code, which is no longer needed, for the CS4227 chip. Jean Sacren fixes kernel documentation for ixgbe. Alex Duyck fixes an fm10k and ixgbe issue in which the polling routine would increase the budget for receive to at least 1 per queue if multiple queues were present. This would result in receive packets being processed when the budget was 0 which is meant to indicate that no receive can be handled. Also fixes an ixgbevf performance issue where netperf test will starve for memory in the time form one transmit interrupt to the next, so limit lowest interrupt rate for adaptive interrupt moderation to 12K. Fixed up ixgbe and ixgbevf to use napi_schedule_irqoff() where the drivers were run from hard interrupt context or with interrupts already disabled in netpoll. Jesse fixes a compiler warning about an unused variable for i40evf. John Greene fixes an issue with ixgbevf, where if the VF driver is loaded while the corresponding PH interface is down, the driver assigns a random MAC address, can be overwritten with the value of hw->mac.perm_addr which is 0 at that point. So avoid this case by initializing hw->mac.perm_addr to the randomly generated address and do not set it unless we receive an ACK from ixgbe. Rasmus Villemoes cleans up some confusing code in i40e debugfs code. ==================== Signed-off-by:

Nikolay Aleksandrov says: ==================== net: ipmr: cleanups and minor improvements Since I'll have to work with ipmr, I decided to clean it up and do some minor improvements. Functionally there're almost no changes except the SLAB_PANIC removal. Most of the patches just re-design some functions to be clearer and more concise and try to remove the ifdef web that was inside. There's more information in each commit. This is the first set, the end goal is to introduce complete netlink support and control over the mfc and vif devices. I've tried to test all of the setsockopt/getsockopt options, and also made builds with various ipmr kconfig options turned on and off. v2: change patch 7 to keep SLAB_PANIC and just drop the unnecessary null check ==================== Signed-off-by: -

Add the helper pimsm_enabled() which replaces the old CONFIG_IP_PIMSM define and is used to check if any version of PIM-SM has been enabled. Use a single if defined(CONFIG_IP_PIMSM_V1) || defined(CONFIG_IP_PIMSM_V2) for the pim-sm shared code. This is okay w.r.t IGMPMSG_WHOLEPKT because only a VIFF_REGISTER device can send such packet, and it can't be created if pimsm_enabled() is false. Signed-off-by:

Before mroute_reg_vif_num was defined only if any of the CONFIG_PIMSM_ options were set, but that's not really necessary as the size of the struct is the same in both cases (checked with pahole, both cases size is 3256 bytes) and we can remove some unnecessary ifdefs to simplify the code.

This code is pretty confused. The variable name 'bytes_not_copied' clearly indicates that the programmer knew the semantics of copy_{to,from}_user, but then the return value is checked for being negative and used as a -Exxx return value. I'm not sure this is the proper fix, but at least we get rid of the dead code which pretended to check for access faults. Signed-off-by:Rasmus Villemoes <linux@rasmusvillemoes.dk> Acked-by:

To avoid this case we init hw->mac.perm_addr to the randomly generated address and do not set it unless we receive ACK from ixgbe. Reported-by:

This patch is the ixgbevf version of commit 8ac34f10 "ixgbe: Limit lowest interrupt rate for adaptive interrupt moderation to 12K" The same logic applies here as well as the same results since a netperf test will starve for memory in the time from one Tx interrupt to the next. As a result the ixgbevf driver underperformed when compared to vhost_net. Signed-off-by:

Based on hardware testing, the host interface supports up to 15368 bytes as the maximum frame size. To determine the correct MTU, we subtract 8 for the internal switch tag, 14 for the L2 header, and 4 for the appended FCS header, resulting in 15342 bytes of payload for our maximum MTU on jumbo frames.

It is possible that the PF has not yet assigned resources to the VF. Although rare, this could result in the VF attempting to read queues it does not own and result in FUM or THI faults in the PF. To prevent this, check queue 0 before we continue in init_hw_vf. Signed-off-by:

Phil Sutter says: ==================== improve fault-tolerance of rhashtable runtime-test The following series aims to improve lib/test_rhashtable in different situations: Patch 1 allows the kernel to reschedule so the test does not block too long on slow systems. Patch 2 fixes behaviour under pressure, retrying inserts in non-permanent error case (-EBUSY). Patch 3 auto-adjusts the upper table size limit according to the number of threads (in concurrency test). In fact, the current default is already too small. Patch 4 makes it possible to retry inserts even in supposedly permanent error case (-ENOMEM) to expose rhashtable's remaining problem of -ENOMEM being not as permanent as it is expected to be. Changes since v1: - Introduce insert_retry() which is then used in single-threaded test as well. - Do not retry inserts by default if -ENOMEM was returned. - Rename the retry counter to be a bit more verbose about what it contains. - Add patch 4 as a debugging aid. ==================== Signed-off-by:
