Calculating ASIDs/VMIDs dynamically from arm_smmu_cfg was a neat trick, but the global uniqueness workaround makes it somewhat more awkward, and means we end up having to pass extra state around in certain cases just to keep a handle on the offset. We already have 16 bits going spare in arm_smmu_cfg; let's just precalculate an ASID/VMID, plop it in there, and tidy up the users accordingly. We'd also need something like this anyway if we ever get near to thinking about SVM, so it's no bad thing.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
