sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64. |

A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes. |

sparc64 work.
- 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. |

interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled. |
