Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)
Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day. |

Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant. |

Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory. |

Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first. |

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 |

Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.
Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code. |

Switch over to per vm_t page tables. (breaks ia32 userspace)
Define dummy memcopy() for amd64 and ppc to satisfy compiler.
Get rid of problematic #include <arch/mm/page.h> in mm/page.h.
Indentation fixes and small changes here and there. |

Begin MIPS implementation of 4-level page table interface.
Add email address to each item in doc/AUTHORS.
Correct type names in comments in mm/vm.c.
Introduce ptl0 pointer in vm_t. |

Generic 4-level page tables interface & implementation (review & test).
Implement more architecture dependant macros on IA-32.
Provide fake implementation on IA-64 and MIPS.
Convert map_page_to_frame() to use the new interface.
Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c. |

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. |

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. |

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. |

Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm. |
