2021-08-05RDMA/iw_cxgb4: Fix refcount underflow while destroying cqs.Dakshaja Uppalapati
Previous atomic increment/decrement logic expects the atomic count to be '0' after the final decrement. Replacing atomic count with refcount does not allow that, as refcount_dec() considers count of 1 as underflow and triggers a kernel splat. Fix the current refcount logic by using the usual pattern of decrementing the refcount and test if it is '0' on the final deref in c4iw_destroy_cq(). Use wait_for_completion() instead of wait_event().

2021-08-05drm/amd/display: workaround for hard hang on HPD on native DPQingqing Zhuo
[Why] HPD disable and enable sequences are not mutually exclusive on Linux. For HPDs that spans over 1s (i.e. HPD low = 1s), part of the disable sequence (specifically, a request to SMU to lower refclk) could come right before the call to PHY enable, causing DMUB to access an unresponsive PHY and thus a hard hang on the system.

2021-08-03net: dsa: qca: ar9331: reorder MDIO write sequenceOleksij Rempel
In case of this switch we work with 32bit registers on top of 16bit bus. Some registers (for example access to forwarding database) have trigger bit on the first 16bit half of request and the result + configuration of request in the second half. Without this patch, we would trigger database operation and overwrite result in one run. To make it work properly, we should do the second part of transfer before the first one is done. So far, this rule seems to work for all registers on this switch.

If hns_roce_cmd_use_events() fails then it means that the poll_sem is not obtained, but the poll_sem is released in hns_roce_cmd_use_polling(), this will cause an unlock problem. This is the static checker warning: drivers/infiniband/hw/hns/hns_roce_main.c:926 hns_roce_init() error: double unlocked '&hr_dev->cmd.poll_sem' (orig line 879) Event mode and polling mode are mutually exclusive and resources are separated, so there is no need to process polling mode resources in event mode.

2021-08-02RDMA/cma: Revert INIT-INIT patchMike Marciniszyn
The net/sunrpc/xprtrdma module creates its QP using rdma_create_qp() and immediately post receives, implicitly assuming the QP is in the INIT state and thus valid for ib_post_recv(). The patch noted in Fixes: removed the RESET->INIT modifiy from rdma_create_qp(), breaking NFS rdma for verbs providers that fail the ib_post_recv() for a bad state. This situation was proven using kprobes in rvt_post_recv() and rvt_modify_qp(). The traces showed that the rvt_post_recv() failed before ANY modify QP and that the current state was RESET.
