Subject[PATCH 3/8] arch/tile: header files for the Tile architecture.
This includes the relevant Linux headers in asm/; the low-level
low-level "Tile architecture" headers in arch/, which are
shared with the hypervisor, etc., and are build-system agnostic;
and the relevant hypervisor headers in hv/.

+ * "Lazy" TLB mode is entered when we are switching to a kernel task,

+ * early x86 machines (where the concept originated) you couldn't do
+ * anything short of a full page table install for invalidation, so
+ * handling a remote TLB invalidate required doing a page table
+ * re-install. Someone clearly decided that it was silly to keep
+ * doing this while in "lazy" TLB mode, so the optimization involves
+ * installing the swapper page table instead the first time one
+ * occurs, and clearing the cpu out of cpu_vm_mask, so the cpu running
+ * the kernel task doesn't need to take any more interrupts. At that
+ * point it's then necessary to explicitly reinstall it when context
+ * switching back to the original mm.
+ *
+ * On Tile, we have to do a page-table install whenever DMA is enabled,
+ * so in that case lazy mode doesn't help anyway. And more generally,
+ * we have efficient per-page TLB shootdown, and don't expect to spend
+ * that much time in kernel tasks in general, so just leaving the
+ * kernel task borrowing the old page table, but handling TLB
+ * shootdowns, is a reasonable thing to do. And importantly, this
+ * lets us use the hypervisor's internal APIs for TLB shootdown, which
+ * means we don't have to worry about having TLB shootdowns blocked
+ * when Linux is disabling interrupts; see the page migration code for
+ * an example of where it's important for TLB shootdowns to complete

+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier. All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads. This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies. See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * b = 2;
+ * memory_barrier();
+ * p = &b; q = p;
+ * read_barrier_depends();
+ * d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends(). However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * a = 2;
+ * memory_barrier();
+ * b = 3; y = b;
+ * read_barrier_depends();
+ * x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b". Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+ * in cases like this where there are no data dependencies.

+ * when these occur in a client's interrupt critical section, they must
+ * be delivered through the downcall mechanism.
+ *
+ * A downcall is initially delivered to the client as an INTCTRL_1

+ * immediately invoke the hv_downcall_dispatch service. This service
+ * will not return; instead it will cause one of the client's actual
+ * downcall-handling interrupt vectors to be entered. The EX_CONTEXT
+ * registers in the client will be set so that when the client irets,
+ * it will return to the code which was interrupted by the INTCTRL_1
+ * interrupt.
+ *
+ * Any saving of registers should be done by the actual handling
+ * vectors; no registers should be changed by the INTCTRL_1 handler.
+ * In particular, the client should not use a jal instruction to invoke
+ * the hv_downcall_dispatch service, as that would overwrite the client's
+ * lr register. Note that the hv_downcall_dispatch service may overwrite
+ * one or more of the client's system save registers.

+ * The client must not modify the INTCTRL_1_STATUS SPR. The hypervisor

+ * it when no further downcalls are pending.
+ *
+ * When a downcall vector is entered, the INTCTRL_1 interrupt will be
+ * masked. When the client is done processing a downcall, and is ready
+ * to accept another, it must unmask this interrupt; if more downcalls
+ * are pending, this will cause the INTCTRL_1 vector to be reentered.
+ * Currently the following interrupt vectors can be entered through a
+ * downcall:
+ *

+ * or the desired number of attempts have been made. When used in this
