When building stmmac, it is only possible to select CONFIG_DWMAC_GENERIC, or any of the glue drivers, when CONFIG_STMMAC_PLATFORM is set. The only exception is CONFIG_STMMAC_PCI. When calling of_mdiobus_register(), it will call our ->reset() callback, which is set to stmmac_mdio_reset(). Most of the code in stmmac_mdio_reset() is protected by a "#if defined(CONFIG_STMMAC_PLATFORM)", which will evaluate to false when CONFIG_STMMAC_PLATFORM=m. Because of this, the phy reset gpio will only be pulled when stmmac is built as built-in, but not when built as modules. Fix this by using "#if IS_ENABLED()" instead of "#if defined()".

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-10-31 This series contains a various collection of fixes. Miroslav Lichvar from Red Hat or should I say IBM now? Updates the PHC timecounter interval for igb so that it gets updated at least once every 550 seconds. Ngai-Mint provides a fix for fm10k to prevent a soft lockup or system crash by adding a new condition to determine if the SM mailbox is in the correct state before proceeding. Jake provides several fm10k fixes, first one marks complier aborts as non-fatal since on some platforms trigger machine check errors when the compile aborts. Added missing device ids to the in-kernel driver. Due to the recent fixes, bumped the driver version. I (Jeff Kirsher) fixed a XFRM_ALGO dependency for both ixgbe and ixgbevf. This fix was based on the original work from Arnd Bergmann, which only fixed ixgbe. Mitch provides a fix for i40e/avf to update the status codes, which resolves an issue between a mis-match between i40e and the iavf driver, which also supports the ice LAN driver. Radoslaw fixes the ixgbe where the driver is logging a message about spoofed packets detected when the VF is re-started with a different MAC address. ==================== Signed-off-by: NDavid S.

ALU operations on pointers such as scalar_reg += map_value_ptr are handled in adjust_ptr_min_max_vals(). Problem is however that map_ptr and range in the register state share a union, so transferring state through dst_reg->range = ptr_reg->range is just buggy as any new map_ptr in the dst_reg is then truncated (or null) for subsequent checks. Fix this by adding a raw member and use it for copying state over to dst_reg.

As far as the patches that made it go: - A patch to ignore offline CPUs when calculating AT_HWCAP. This should fix GDB on the HiFive unleashed, which has an embedded core for hart 0 which is exposed to Linux as an offline CPU. - A move of EM_RISCV to elf-em.h, which is where it should have been to begin with. - I've also removed the 64-bit divide routines. I know I'm not really playing by my own rules here because I posted the patches this morning, but since they shouldn't be in the kernel I think it's better to err on the side of going too fast here.

Ido Schimmel says: ==================== mlxsw: Enable minimum shaper on MC TCs Petr says: An MC-aware mode was introduced in commit 7b819530 ("mlxsw: spectrum: Configure MC-aware mode on mlxsw ports"). In MC-aware mode, BUM traffic gets a special treatment by being assigned to a separate set of traffic classes 8..15. Pairs of TCs 0 and 8, 1 and 9, etc., are then configured to strictly prioritize the lower-numbered ones. The intention is to prevent BUM traffic from flooding the switch and push out all UC traffic, which would otherwise happen, and instead give UC traffic precedence. However strictly prioritizing UC traffic has the effect that UC overload pushes out all BUM traffic, such as legitimate ARP queries. These packets are kept in queues for a while, but under sustained UC overload, their lifetime eventually expires and these packets are dropped. That is detrimental to network performance as well. In this patchset, MC TCs (8..15) are configured with minimum shaper of 200Mbps (a minimum permitted value) to allow a trickle of necessary control traffic to get through. First in patch #1, the QEEC register is extended with fields necessary to configure the minimum shaper. In patch #2, minimum shaper is enabled on TCs 8..15. In patches #3 and #4, first the MC-awareness test is tweaked to support the minimum shaper, and then a new test is introduced to test that MC traffic behaves well under UC overload. ==================== Signed-off-by: NDavid S.

It is not necessary to reset the queue in the hns3_uninit_all_ring(), since the queue is stopped in the down operation, and will be reset in the up operation. And the judgment of the HCLGE_STATE_RST_HANDLING flag in the hclge_reset_tqp() is not correct, because we need to reset tqp during pf reset, otherwise it may cause queue not being reset to working state problem.

The spin lock of the command queue only need to be initialized once when the driver initializes the command queue. It is not necessary to initialize the spin lock when resetting. At the same time, the modification of the queue member should be performed after acquiring the lock.

The current driver supports handling two vector0 interrupts, reset and mailbox. When the hardware reports an interrupt of another type of interrupt source, if the driver does not process the interrupt, but enables the interrupt, the hardware will repeatedly report the unknown interrupt. Therefore, the driver enables the vector0 interrupt after clearing the known type of interrupt source. Other conditions are not enabled.

When hns3_get_ring_config()/hns3_queue_to_ring()/ hns3_get_vector_ring_chain() failed during resetting, the allocated memory has not been freed before these three functions return. So this patch adds error handler in these functions to fix it.
