Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable. |

ia64 work.
Comment some offending steps of heavyweight interrupt handler regarding RSE switching.
With this change, ia64 will do well on tests rwlock #4 and thread #1.
Cleanup. |

Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.
ia64 work.
Better General Exception handler. |

ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.
ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement. |

IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address. |

Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions. |

Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority. |

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(). |

For all relevant architectures, rename fake.s to dummy.s to better reflect the purpose of the file.
Also define global symbol called dummy. |

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. |

IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.
Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.
Minor cosmetics through out the code.
Changes in linker scripts. |
