The vcpu mmap area may consist of more than just the kvm_run struct. Allocate enough space for the entire vcpu mmap area. Without this, on x86, the PIO page, for example, will be missing. This is problematic when dealing with an unhandled exception from the guest as the exception vector will be incorrectly reported as 0x0.

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.
