Add a clocksource ID for TSC and a distinct one for the early TSC. Use distinct IDs for TSC and early TSC, since those also have distinct clocksource structs. This should help to keep existing semantics when comparing clocksources. Also, set the recently added struct system_counterval_t member cs_id to the TSC ID in the cases where the clocksource member is being set to the TSC clocksource. In the future, get_device_system_crosststamp() will compare the clocksource ID in struct system_counterval_t, rather than the clocksource. For the x86 ART related code, system_counterval_t.cs == NULL corresponds to system_counterval_t.cs_id == CSID_GENERIC (0).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
