2018-09-04net: phy: mscc: factorize function for getting LED mode from DTQuentin Schulz
Microsemi PHYs support different LED modes depending on the variant, so let's factorize the code so we just have to give the supported modes while the logic behind getting the mode remains identical.

2018-09-04net: phy: mscc: factorize code for LEDs modeQuentin Schulz
LEDs modes are set the same way, except they are offset by 4 times the index of the LED. Let's factorize all the code so that it's easier to add support for the 4 LEDs of the VSC8584 PHY. Signed-off-by: Quentin Schulz <quentin.schulz@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-09-04dm verity: fix crash on bufio buffer that was allocated with vmallocMikulas Patocka
Since commit d1ac3ff008fb ("dm verity: switch to using asynchronous hash crypto API") dm-verity uses asynchronous crypto calls for verification, so that it can use hardware with asynchronous processing of crypto operations. These asynchronous calls don't support vmalloc memory, but the buffer data can be allocated with vmalloc if dm-bufio is short of memory and uses a reserved buffer that was preallocated in dm_bufio_client_create(). Fix verity_hash_update() so that it deals with vmalloc'd memory correctly.

2018-09-04drm/i915/gvt: Fix life cycle reference on KVM mmZhenyu Wang
Handle guest mm access life cycle properly with mmget()/mmput(). As noted by Linus, use_mm() depends on valid live page table but KVM's mmgrab() doesn't guarantee that. As vGPU usage depends on guest VM life cycle, need to make sure to use mmget()/mmput() to guarantee VM address access. v3: fix build v2: v1 caused a weird dependence issue which failed for vfio device release, which result invalid mdev vgpu and kvm state without proper release taken. This trys to put right reference around VM address space access instead.

2018-09-03net: hns3: Change the dst mac addr of loopback packetYunsheng Lin
Currently, the dst mac addr of loopback packet is the same as the host' mac addr, the SSU component may loop back the packet to host before the packet reaches mac or serdes, which will defect the purpose of mac or serdes selftest. This patch changes it by adding 0x1f to the last byte of dst mac addr.

2018-09-03net: hns3: Preserve vlan 0 in hardware tableYunsheng Lin
When netdev is down, the stack will delete the vlan from hardware including vlan0, which will cause problem when doing loopback selftest when netdev is down. This patch fixes it by always preserving vlan 0 in hardware, because vlan 0 is defalut vlan, which should always be in hardware.

Tqp and mac need to be enabled when doing loopback selftest, ae_algo->ops->start/stop is used to do the job, there is a time window between ae_algo->ops->start/stop and loopback setup, which will cause selftest failed problem when there is frame coming in during that time window.

2018-09-03net: hns3: Fix error of checking used vlan idJian Shen
PF uses hdev->vlan_table to manage the port vlan table. In function hclge_set_vlan_filter_hw(), it checks whether a vlan id has been used, by foreach all the vport bits. It should use macro HCLGE_VPORT_NUM, not VLAN_N_VID as the foreach condition.

2018-09-03net: hns3: Fix for vf vlan delete failed problemYunsheng Lin
There are only 128 entries in vf vlan table, if user has added more than 128 vlan, fw will ignore it and disable the vf vlan table. So when user deletes the vlan entry that has not been set to vf vlan table, fw will return not found result and driver treat that as error, which will cause vlan delete failed problem. This patch fixes it by returning ok when fw returns not found result.
