* @data_uptr: User pointer to an array of driver-specific cache invalidation
* data.
* @data_type: One of enum iommu_hwpt_invalidate_data_type, defining the data
* type of all the entries in the invalidation request array. It
* should be a type supported by the hwpt pointed by @hwpt_id.
* @entry_len: Length (in bytes) of a request entry in the request array
* @entry_num: Input the number of cache invalidation requests in the array.
* Output the number of requests successfully handled by kernel.
* @__reserved: Must be 0.
*
* Invalidate the iommu cache for user-managed page table. Modifications on a
* user-managed page table should be followed by this operation to sync cache.
* Each ioctl can support one or more cache invalidation requests in the array
* that has a total size of @entry_len * @entry_num.
*
* An empty invalidation request array by setting @entry_num==0 is allowed, and
* @entry_len and @data_uptr would be ignored in this case. This can be used to
* check if the given @data_type is supported or not by kernel.
