sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places
OpenFirmware work:
- two new functions for walking the device tree
Generic boot loader work:
- added basic string functions
Usual pile of indentation and formatting fixes. |

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... |

Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation. |

CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp(). |

frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed |

Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems. |

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.
sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop. |

Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed. |

Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code. |

Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory. |
