kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone() |

make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64 |

Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely. |

Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented. |

remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability) |

Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be. |

Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur. |

Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.
Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary. |

Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true. |
