All we're really doing is incrementing a simple counter in a doorbell_info struct. We can do without extra variables and a separate counter kept in guc_client. Since it's gone, we're also removing its debugfs. The only functional change here, is that we're no longer treating 0 as a special value. GuC doesn't seem to care, why should we? v2: Restore desc->tail update. v3: Drop the retry loop, assert that doorbell cookie doesn't change behind our back. v4: WARN rather than BUG, use xchg.

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.
