[ Upstream commit c4b4d7047f16a8d138ce76da65faefb7165736f2 ] This patch fixes a bug where GEN1 VMs doesn't allow resolutions greater than 64 MB size (eg 7680x4320). Unnecessary PCI check limits Gen1 VRAM to legacy PCI BAR size only (ie 64MB). Thus any, resolution requesting greater then 64MB (eg 7680x4320) would fail. MMIO region assigning this memory shouldn't be limited by PCI bar size.

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.
