Currently kvm_get_inst() returns KVM_INVALID_INST in the event of a fault reading the guest instruction. This has the rather arbitrary magic value 0xdeadbeef. This API isn't very robust, and in fact 0xdeadbeef is a valid MIPS64 instruction encoding, namely "ld t1,-16657(s5)". Therefore change the kvm_get_inst() API to return 0 or -EFAULT, and to return the instruction via a u32 *out argument. We can then drop the KVM_INVALID_INST definition entirely.

README
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.
