IOMMU Fixes for Linux v5.10-rc2
Including:
- Fix a NULL-ptr dereference in the Intel VT-d driver
- Two fixes for Intel SVM support
- Increase IRQ remapping table size in the AMD IOMMU driver. The
old number of 128 turned out to be too low for some recent
devices.
- Fix a mask check in generic IOMMU code
iommu: Fix a check in iommu_check_bind_data()
The "data->flags" variable is a u64 so if one of the high 32 bits is
set the original code will allow it, but it should be rejected. The
fix is to declare "mask" as a u64 instead of a u32.
