When mapping a framebuffer object, the virtual memory area (VMA)
offset ('vm_pgoff') should be adjusted by the start of the
'vma_node' associated with the object. This ensures that the VMA
offset is correctly aligned with the corresponding offset within
the GGTT aperture.
Increment vm_pgoff by the start of the vma_node with the offset=
provided by the user.

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.
