Made powerpc to get on PearPC to the version print when compiled with -O1:
- create proper memory zones
- switch to real mode on boot
TODO
- kernel relocation during boot
- autodetection of framebuffer settings (PCI?) - now includes hardcoded
settings for PearPc. |

mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.
Remove GET_PTL0_ADDRESS from kernel.
Update sparc64 comments in barrier.h. |

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |

New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |

/kernel/trunk/ |
Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping(). |

We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning. |

Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.

mipsel -EB does not behave correctly.
