commit 4900dda90af2cb13bc1d4c12ce94b98acc8fe64e upstream. If a MMU is shared between multiple GPUs, all of them need to flush their TLBs, so a single marker that gets reset on the first flush won't do. Replace the flush marker with a sequence number, so that it's possible to check if the TLB is in sync with the current page table state for each GPU.

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.
