SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism. |

Implemented preemptible trap handler for userspace (including syscalls - did not forget enabling interrupts for them) and the ralated stuff. Implemented handlers of instruction/data MMU miss/protection. Now some userspace tasks are run; there are, however, still some bugs causing unexpected data MMU misses. |

Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions. |

Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization). |

The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB. |

Introduce FRAME_LOW_16_GiB slab/frame allocator flag. When specified, the
allocators will not allocate memory above 16 GiB. Each architecture needs to
make sure not to merge zones from below and above 16 GiB. Allocations that
require memory below 16 GiB need to be altered to use this flag. |

Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it. |

Finer grained waiting for memory with consideration of the number
of available memory frames. |

Get rid of the infamous "Sleep not implemented" panic during low memory
condition. Use a condition variable to implement the sleep. As of now, the
condition is rather coarse and can cause that threads may sleep unnecessarily.
Needs to be fine tuned and based on the amount of memory available. |

Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement. |
