Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock. |

Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog. |

task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space. |

Fix programming of local APIC timer to interrupt the processor
in the proper relation to HZ. (Was hardcoded to be each 1ms,
but should have been each 10ms). |

Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.

Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault. |

Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar(). |

case when the frame buffer size is below FRAME_SIZE. |

zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas. |

/kernel/trunk/ |
Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |

When seting TSS limit, take the mandatory extra ending byte with all bits set into account.
Align this group of eight bits on byte boundary. |

Fixes in amd64 and ia32 ddi_iospace_enable_arch(). |
|

/kernel/trunk/ |
Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it. |

The general protection fault handler now contains
code to service early I/O Permission bitmap faults. |

I/O Permission bitmap fixes. The trailing all-one sequence must be 8 bits long.

Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there. |

This patch enables 32 base of GDT on APs at boot. It should now be able to use GDTs allocated up of 16MB so I hope this patches AP crash bug ocurred in some memory configurations. |

Reorganize syscall names to better correspond to kernel architecture.

SYS_AS_AREA_SHARE_PERFORM syscalls. |
