There are three issues in nested_vmx_check_exception: 1) it is not taking PFEC_MATCH/PFEC_MASK into account, as reported by Wanpeng Li; 2) it should rebuild the interruption info and exit qualification fields from scratch, as reported by Jim Mattson, because the values from the L2->L0 vmexit may be invalid (e.g. if an emulated instruction causes a page fault, the EPT misconfig's exit qualification is incorrect). 3) CR2 and DR6 should not be written for exception intercept vmexits (CR2 only for AMD). This patch fixes the first two and adds a comment about the last, outlining the fix.

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.
