Support access to VMware backdoor requires KVM to intercept #GP exceptions from guest which introduce slight performance hit. Therefore, control this support by module parameter. Note that module parameter is exported as it should be consumed by kvm_intel & kvm_amd to determine if they should intercept #GP or not. This commit doesn't change semantics. It is done as a preparation for future commits.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
