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.
- Convert interrupt_vector trap handler and some mm related trap handlers to
use preemptibe_handler(), which is essential for traps coming from userspace.
- Add fast_data_access_protection() handler. |

sparc64 work.
Bunch of changes in preparation for sparc64 mm and userspace support.
Fix alignment of hardcoded_* variables in linker script. |

sparc64 work.
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. |

i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace. |

Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.
The repository won't compile now. To be fixed in next commits. |

Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data. |

Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing. |

Remove OpenFirmware calls from kernel/ entirely.
Switch the sparc64 port to use bootinfo.
Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace. |

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... |
