Cleanup.
Cancel __fake in pm.c and replace it with LONG(0xdeadbeaf) in linker script. Still need some to find out why it must be there.
Remove comment saying, that mips is little-endian. |

Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests. |

Cleanup of makefiles to have common options in one main makefile.
Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.
There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now. |

MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet. |

Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy(). |

1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option |

Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t. |

Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.
Fix heap initialization to take 'heap_delta' into account.
Implement IA-64 get_stack_base().
Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).
More #include cleanup. |

Add some comments to IA-32 src/boot/boot.S and src/smp.S.
Make the boot stack start on page boundary.
This is required by get_stack_base().
Define 'THE' macro.
Implement preemption_disable() and preemption_enable().
Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.
Reduction of many #include paths. |

Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy. |
