sparc64 work.
- Modify before_thread_runs_arch() to store addresses of the kernel stack and
userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.
- Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
- Implement trap handler for spilling register windows into userspace window buffer.
- Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
- Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes. |

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(). |

remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work) |

For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).
New mips32 atomic_add() function.
Cleanup. |

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. |

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. |
