x86: Mishandling of instruction pointer truncation during emulation

ISSUE DESCRIPTION When emulating HVM instructions, Xen uses a small i-cache for fetches from guest memory. The code that handles cache misses does not check if the address from which it fetched lies within the cache before blindly writing to it. As such it is possible for the guest to overwrite...
