2022-12-05iommu/vt-d: Fix buggy QAT device maskJacob Pan
Impacted QAT device IDs that need extra dtlb flush quirk is ranging from 0x4940 to 0x4943. After bitwise AND device ID with 0xfffc the result should be 0x4940 instead of 0x494c to identify these devices.

2022-12-05vfio: Move vfio group specific code into group.cYi Liu
This prepares for compiling out vfio group after vfio device cdev is added. No vfio_group decode code should be in vfio_main.c, and neither device->group reference should be in vfio_main.c.

2022-12-05vfio: Refactor vfio_device open and closeYi Liu
This refactor makes the vfio_device_open() to accept device, iommufd_ctx pointer and kvm pointer. These parameters are generic items in today's group path and future device cdev path. Caller of vfio_device_open() should take care the necessary protections. e.g. the current group path need to hold the group_lock to ensure the iommufd_ctx and kvm pointer are valid. This refactor also wraps the group spefcific codes in the device open and close paths to be paired helpers like: - vfio_device_group_open/close(): call vfio_device_open/close() - vfio_device_group_use/unuse_iommu(): this pair is container specific. iommufd vs. container is selected in vfio_device_first_open(). Such helpers are supposed to be moved to group.c. While iommufd related codes will be kept in the generic helpers since future device cdev path also need to handle iommufd.

2022-12-05vfio: Swap order of vfio_device_container_register() and open_device()Yi Liu
This makes the DMA unmap callback registration to container be consistent across the vfio iommufd compat mode and the legacy container mode. In the vfio iommufd compat mode, this registration is done in the vfio_iommufd_bind() when creating access which has an unmap callback. This is prior to calling the open_device() op. The existing mdev drivers have been converted to be OK with this order. So it is ok to swap the order of vfio_device_container_register() and open_device() for legacy mode. This also prepares for further moving group specific code into separate source file.

2022-12-05vfio: Move the sanity check of the group to vfio_create_group()Jason Gunthorpe
This avoids opening group specific code in __vfio_register_dev() for the sanity check if an (existing) group is not corrupted by having two copies of the same struct device in it. It also simplifies the error unwind for this sanity check since the failure can be detected in the group allocation. This also prepares for moving the group specific code into separate group.c.

2022-12-05staging: r8188eu: use ieee80211 helper for protected bitMartin Kaiser
Use ieee80211_has_protected to check if the "protected" bit is set. Remove the r8188eu driver's internal macro for this check.

2022-12-05staging: r8188eu: simplify the checks for zero addressMartin Kaiser
In function ap2sta_data_frame, we can use is_zero_ether_addr to check for all-zero ethernet addresses. Both pattrib->bssid and mybssid are 16-bit aligned.

2022-12-05staging: r8188eu: fix the number of probereq retriesMartin Kaiser
issue_probereq_ex sends a probe request and retries if this fails. There's no point in making the number of retries configurable. Hard-code the value that's used by issue_probereq_ex's only caller. Simplify the code to check the loop condition only once.
