- Modify before_thread_runs_arch() to store addresses of the kernel stack and
userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.
- Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
- Implement trap handler for spilling register windows into userspace window buffer.
- Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
- Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes. |

Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.
Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer. |

Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.
A lot of formatting and indentation fixes. |

Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.
Little bit of formatting and indentation. |

Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares... |
