Linux kernel source tree

Don't check for flat ccs from VF-level as VF does not have direct access to the register. If the BIOS disables FlatCCS support (a use-case that will nearly never be used) and the has_flat_ccs flag is set, there shouldn't be any functional impact. The hardware will drop writes to the CCS region, and reads from the CCS region will always return 0. For the native case, the flag is disabled if the BIOS disables it to avoid unnecessary overhead in buffer object (BO) creation and migration.

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 reStructuredText 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.
