so for every module you propose to add a thread, handling the IPC work queue and then when an IPC arrives, the submitter changes to the module domain, submits the IPC to the work queue, after which it's processed by the queue thread?

The thread is created for a security domain, which will include multiple modules from a single vendor.

Add helper functions user_add_memory and user_remove_memory that allows to add/remove memory regions from the memory domain. The purpose of these functions is to round addresses appropriately for the memory domain.

The non-privileged modules code should be executed in separate thread executed in userspace mode. This way the code and data owned by such module will be isolated from other non-privileged modules in the system. The implementation creates user_work_queue threads that will service all IPC's for all such modules. There are security domains defined that will combines service of IPC's for modules that could exist without isolation (eg. several instances of the same module or modules originating from single vendor).
