There is no reason to open code what the switch setup function does, in fact, because we just issued a switch reset, we would make all the register get their default values, including for instance, having unused port be enabled again and wasting power and leading to an inappropriate switch core clock being selected.

2018-10-11net: dsa: bcm_sf2: Fix unbind orderingFlorian Fainelli
The order in which we release resources is unfortunately leading to bus errors while dismantling the port. This is because we set priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now permissible to clock gate the switch. Later on, when dsa_slave_destroy() comes in from dsa_unregister_switch() and calls dsa_switch_ops::port_disable, we perform the same dismantling again, and this time we hit registers that are clock gated. Make sure that dsa_unregister_switch() is the first thing that happens, which takes care of releasing all user visible resources, then proceed with clock gating hardware. We still need to set priv->wol_ports_mask to 0 to make sure that an enabled port properly gets disabled in case it was previously used as part of Wake-on-LAN.

2018-10-11r8169: set RX_MULTI_EN bit in RxConfig for 8168F-family chipsMaciej S. Szmigiero
It has been reported that since commit 05212ba8132b42 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices") at least RTL_GIGA_MAC_VER_38 NICs work erratically after a resume from suspend. The problem has been traced to a missing RX_MULTI_EN bit in the RxConfig register. We already set this bit for RTL_GIGA_MAC_VER_35 NICs of the same 8168F chip family so let's do it also for its other siblings: RTL_GIGA_MAC_VER_36 and RTL_GIGA_MAC_VER_38. Curiously, the NIC seems to work fine after a system boot without having this bit set as long as the system isn't suspended and resumed.

2018-10-11net/mlx4_core: Fix warnings during boot on driverinit param set failuresMoshe Shemesh
During boot, mlx4_core sets the driverinit configuration parameters and updates the devlink module on the initial values calling devlink_param_driverinit_value_set(). If devlink_param_driverinit_value_set() returns an error mlx4_core reports kernel module warning. This caused false alarm during boot in case kernel was compiled with CONFIG_NET_DEVLINK off. Fix by removing warning reported in case devlink_param_driverinit_value_set() fails. This actually makes the function mlx4_devlink_set_init_value() redundant to using directly devlink_param_driverinit_value_set() and so removed. It fixes the following kernel trace: mlx4_core 0000:00:06.0: devlink set parameter 0 value failed (err = -95) mlx4_core 0000:00:06.0: devlink set parameter 1 value failed (err = -95) mlx4_core 0000:00:06.0: devlink set parameter 4 value failed (err = -95) mlx4_core 0000:00:06.0: devlink set parameter 5 value failed (err = -95) mlx4_core 0000:00:06.0: devlink set parameter 3 value failed (err = -95) Fixes: bd1b51dc66df ("mlx4: Add mlx4 initial parameters table and register it") Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

2018-10-10dm linear: eliminate linear_end_io call if CONFIG_DM_ZONED disabledMike Snitzer
It is best to avoid any extra overhead associated with bio completion. DM core will indirectly call a DM target's .end_io if it is defined. In the case of DM linear, there is no need to do so (for every bio that completes) if CONFIG_DM_ZONED is not enabled. Avoiding an extra indirect call for every bio completion is very important for ensuring DM linear doesn't incur more overhead that further widens the performance gap between dm-linear and raw block devices.

2018-10-10pinctrl: mcp23s08: fix irq and irqchip setup orderMarco Felsch
Since 'commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' the irq request isn't the last devm_* allocation. Without a deeper look at the irq and testing this isn't a good solution. Since this driver relies on the devm mechanism, requesting a interrupt should be the last thing to avoid memory corruptions during unbinding. 'Commit 02e389e63e35 ("pinctrl: mcp23s08: fix irq setup order")' fixed the order for the interrupt-controller use case only. The mcp23s08_irq_setup() must be split into two to fix it for the interrupt-controller use case and to register the irq at last. So the irq will be freed first during unbind.

2018-10-10gpio: Assign gpio_irq_chip::parents to non-stack pointerStephen Boyd
gpiochip_set_cascaded_irqchip() is passed 'parent_irq' as an argument and then the address of that argument is assigned to the gpio chips gpio_irq_chip 'parents' pointer shortly thereafter. This can't ever work, because we've just assigned some stack address to a pointer that we plan to dereference later in gpiochip_irq_map(). I ran into this issue with the KASAN report below when gpiochip_irq_map() tried to setup the parent irq with a total junk pointer for the 'parents' array.

Use ret as memcpy len to fix this. The old code was using ec_dev->event_size, which is the event payload/data size excluding event_type header, for the length of the memcpy operation.

2018-10-09dm: fix report zone remapping to account for partition offsetDamien Le Moal
If dm-linear or dm-flakey are layered on top of a partition of a zoned block device, remapping of the start sector and write pointer position of the zones reported by a report zones BIO must be modified to account for the target table entry mapping (start offset within the device and entry mapping with the dm device). If the target's backing device is a partition of a whole disk, the start sector on the physical device of the partition must also be accounted for when modifying the zone information. However, dm_remap_zone_report() was not considering this last case, resulting in incorrect zone information remapping with targets using disk partitions. Fix this by calculating the target backing device start sector using the position of the completed report zones BIO and the unchanged position and size of the original report zone BIO. With this value calculated, the start sector and write pointer position of the target zones can be correctly remapped.

2018-10-07mach64: detect the dot clock divider correctly on sparcMikulas Patocka
On Sun Ultra 5, it happens that the dot clock is not set up properly for some videomodes. For example, if we set the videomode "r1024x768x60" in the firmware, Linux would incorrectly set a videomode with refresh rate 180Hz when booting (suprisingly, my LCD monitor can display it, although display quality is very low). The reason is this: Older mach64 cards set the divider in the register VCLK_POST_DIV. The register has four 2-bit fields (the field that is actually used is specified in the lowest two bits of the register CLOCK_CNTL). The 2 bits select divider "1, 2, 4, 8". On newer mach64 cards, there's another bit added - the top four bits of PLL_EXT_CNTL extend the divider selection, so we have possible dividers "1, 2, 4, 8, 3, 5, 6, 12". The Linux driver clears the top four bits of PLL_EXT_CNTL and never sets them, so it can work regardless if the card supports them. However, the sparc64 firmware may set these extended dividers during boot - and the mach64 driver detects incorrect dot clock in this case. This patch makes the driver read the additional divider bit from PLL_EXT_CNTL and calculate the initial refresh rate properly.
