KVM: x86: Generate set of VMX feature MSRs using first/last definitions
Add VMX MSRs to the runtime list of feature MSRs by iterating over the range of emulated MSRs instead of manually defining each MSR in the "all" list. Using the range definition reduces the cost of emulating a new VMX MSR, e.g. prevents forgetting to add an MSR to the list. Extracting the VMX MSRs from the "all" list, which is a compile-time constant, also shrinks the list to the point where the compiler can heavily optimize code that iterates over the list. No functional change intended.

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.
