Replace confusing comment in scheduler.c.
Add warning/explanatory comment to arch.h saying that CPU, THREAD and TASK macros are preemption-unsafe. |

Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.
Tiny changes here and there. |

Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().
Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT. |

Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size. |

SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.
Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.
Usual cosmetics. |

Define two placeholder functions for atomic_inc and atomic_dec on IA-64.
Add Ondrej Palkovsky to doc/AUTHORS.
Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken) |

Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture. |

SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.
MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment. |

Discard 'copy' parameter of map_page_to_frame().
Introduce 'root' parameter of map_page_to_frame().
If 'root' is zero, page directory address is read from CPU.
Otherwise 'root' is used as page directory address.
Add missing word to new doxygen-style comments in scheduler.c. |

IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.
Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.
Minor cosmetics through out the code.
Changes in linker scripts. |

Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.
Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.
Cosmetic changes here and there. |

IA-64 work.
Redefine FRAME_SIZE to "(16*1024)" instead of "2*4096". Note that the latter definition was wrong because of the lack of "()".
Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S.
Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init().
In start.S, write r0 to ar.bspstore.
Janitorial fixes.
Add count_t type.
Replace several occurrences of int and __u32 by count_t or size_t.
Shorten several panic strings. |

Add context_set() macro to support extended behaviour for architectures with more than one stack (e.g. IA-64).
Now there is one generic context_set() defined in include/context.h and one IA-64 specific defined in arch/ia64/include/context.h. |

FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.
Re-enable O3 again.
Revert Makefile.config not to compile in any tests. |

Add pi calculation to FPU test #1. |
