mainlining shenanigans

Now that we have GVA page tables and an optimised TLB refill handler in place, convert the handling of commpage faults from the guest kernel to fill the GVA page table and invalidate the TLB entry, rather than filling the wired TLB entry directly. For simplicity we no longer use a wired entry for the commpage (refill should be much cheaper with the fast-path handler anyway). Since we don't need to manipulate the TLB directly any longer, move the function from tlb.c to mmu.c. This puts it closer to the similar functions handling KSeg0 and TLB mapped page faults from the guest.

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.
