Do not allocate full page for the uspace window buffer.
Instead, allocate only the bare minimum to fit NWINDOWS - 1
uspace windows and to satisfy alignment requirements. |

Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code. |

- Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.
- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.
- More TSB work on the sparc64 front. |

Revert last change.
The register window save area is automatically allocated by the SAVE instruction. |

Even the first kernel register window after the switch from userspace stack needs
proper register window save area [sparc64]. |

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.
More bits needed to reach the userspace milestone were added.
The preemptible_handler(), still a prototype, now contains all functionality it needs.
Some sanitation was added to functions expecting page-aligned pointers to
userspace window buffer. |

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. |

sparc64 work.
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. |
