Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|

Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|

Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared). |

Remove WAKEUP_IPI stuff.
Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL. |

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |

Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |

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(). |

Fixes of configuration program. |

Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.
Other.

MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
