Reworked handling of illegal virtual aliases caused by frame reuse.
We moved the incomplete handling from backend's frame method to
backend's page_fault method. The page_fault method is the one that
can create an illegal alias if it writes the userspace frame using
kernel address with a different page color than the page to which is
this frame mapped in userspace. When we detect this, we do D-cache
shootdown on all processors (!!!).
If we add code that accesses userspace memory from kernel address
space, we will have to check for illegal virtual aliases at all such
places.
I tested this on a 4-way simulated E6500 and a real-world Ultra 5,
which has unfortunatelly only one processor.
This solves ticket #26. |

Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered. |

no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context. |

Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
