Following a similar reinstate for the KSZ9031. Older kernels would use the genphy_soft_reset if the PHY did not implement a .soft_reset. Bluntly removing that default may expose a lot of situations where various PHYs/board implementations won't recover on various changes. Like with this implementation during a 4.9.x to 5.4.x LTS transition. I think it's a good thing to remove unwanted soft resets but wonder if it did open a can of worms?

2021-02-25drm/rockchip: Require the YTR modifier for AFBCAlyssa Rosenzweig1-0/+11
The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption. The upstream AFBC support was developed against a captured frame, which failed to exercise modifier support. Prior to bring-up of AFBC in Mesa (in the Panfrost driver), no open userspace respected modifier reporting. As such, this change is not expected to affect broken userspaces. Tested on RK3399 with Panfrost and Weston.

2021-02-24ibmvnic: fix a race between open and resetSukadev Bhattiprolu1-8/+55
__ibmvnic_reset() currently reads the adapter->state before getting the rtnl and saves that state as the "target state" for the reset. If this read occurs when adapter is in PROBED state, the target state would be PROBED. Just after the target state is saved, and before the actual reset process is started (i.e before rtnl is acquired) if we get an ibmvnic_open() call we would move the adapter to OPEN state. But when the reset is processed (after ibmvnic_open()) drops the rtnl), it will leave the adapter in PROBED state even though we already moved it to OPEN. To fix this, use the RTNL to improve serialization when reading/updating the adapter state. i.e determine the target state of a reset only after getting the RTNL. And if a reset is in progress during an open, simply set the target state of the adapter and let the reset code finish the open (like we currently do if failover is pending). One twist to this serialization is if the adapter state changes when we drop the RTNL to update the link state. Account for this by checking if there was an intervening open and update the target state for the reset accordingly (see new comments in the code). Note that only the reset functions and ibmvnic_open() can set the adapter to OPEN state and this must happen under rtnl.

2021-02-24net: introduce CAN specific pointer in the struct net_deviceOleksij Rempel4-4/+12
Since 20dd3850bcf8 ("can: Speed up CAN frame receiption by using ml_priv") the CAN framework uses per device specific data in the AF_CAN protocol. For this purpose the struct net_device->ml_priv is used. Later the ml_priv usage in CAN was extended for other users, one of them being CAN_J1939. Later in the kernel ml_priv was converted to an union, used by other drivers. E.g. the tun driver started storing it's stats pointer. Since tun devices can claim to be a CAN device, CAN specific protocols will wrongly interpret this pointer, which will cause system crashes. Mostly this issue is visible in the CAN_J1939 stack. To fix this issue, we request a dedicated CAN pointer within the net_device struct.

2021-02-24mm: memcg: add swapcache stat for memcg v2Shakeel Butt1-0/+6
This patch adds swapcache stat for the cgroup v2. The swapcache represents the memory that is accounted against both the memory and the swap limit of the cgroup. The main motivation behind exposing the swapcache stat is for enabling users to gracefully migrate from cgroup v1's memsw counter to cgroup v2's memory and swap counters. Cgroup v1's memsw limit allows users to limit the memory+swap usage of a workload but without control on the exact proportion of memory and swap. Cgroup v2 provides separate limits for memory and swap which enables more control on the exact usage of memory and swap individually for the workload. With some little subtleties, the v1's memsw limit can be switched with the sum of the v2's memory and swap limits. However the alternative for memsw usage is not yet available in cgroup v2. Exposing per-cgroup swapcache stat enables that alternative. Adding the memory usage and swap usage and subtracting the swapcache will approximate the memsw usage. This will help in the transparent migration of the workloads depending on memsw usage and limit to v2' memory and swap counters. The reasons these applications are still interested in this approximate memsw usage are: (1) these applications are not really interested in two separate memory and swap usage metrics. A single usage metric is more simple to use and reason about for them. (2) The memsw usage metric hides the underlying system's swap setup from the applications. Applications with multiple instances running in a datacenter with heterogeneous systems (some have swap and some don't) will keep seeing a consistent view of their usage.

2021-02-24mm: memcontrol: convert NR_FILE_PMDMAPPED account to pagesMuchun Song1-2/+1
Currently we use struct per_cpu_nodestat to cache the vmstat counters, which leads to inaccurate statistics especially THP vmstat counters. In the systems with hundreds of processors it can be GBs of memory. For example, for a 96 CPUs system, the threshold is the maximum number of 125. And the per cpu counters can cache 23.4375 GB in total. The THP page is already a form of batched addition (it will add 512 worth of memory in one go) so skipping the batching seems like sensible. Although every THP stats update overflows the per-cpu counter, resorting to atomic global updates. But it can make the statistics more accuracy for the THP vmstat counters. So we convert the NR_FILE_PMDMAPPED account to pages. This patch is consistent with 8f182270dfec ("mm/swap.c: flush lru pvecs on compound page arrival"). Doing this also can make the unit of vmstat counters more unified. Finally, the unit of the vmstat counters are pages, kB and bytes. The B/KB suffix can tell us that the unit is bytes or kB. The rest which is without suffix are pages.

2021-02-24mm: memcontrol: convert NR_SHMEM_THPS account to pagesMuchun Song1-2/+1
Currently we use struct per_cpu_nodestat to cache the vmstat counters, which leads to inaccurate statistics especially THP vmstat counters. In the systems with hundreds of processors it can be GBs of memory. For example, for a 96 CPUs system, the threshold is the maximum number of 125. And the per cpu counters can cache 23.4375 GB in total. The THP page is already a form of batched addition (it will add 512 worth of memory in one go) so skipping the batching seems like sensible. Although every THP stats update overflows the per-cpu counter, resorting to atomic global updates. But it can make the statistics more accuracy for the THP vmstat counters. So we convert the NR_SHMEM_THPS account to pages. This patch is consistent with 8f182270dfec ("mm/swap.c: flush lru pvecs on compound page arrival"). Doing this also can make the unit of vmstat counters more unified. Finally, the unit of the vmstat counters are pages, kB and bytes. The B/KB suffix can tell us that the unit is bytes or kB. The rest which is without suffix are pages.
