Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread. |

Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep(). |

/kernel/trunk/generic/ |
Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings. |

Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows. |
|

/kernel/trunk/ |
Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.) |
|

/kernel/trunk/generic/ |
Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier. |

Fix comments. |

CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp(). |

/kernel/trunk/ |
Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction). |
|

Basic futex. Prototype implementation. |
|

Small atomic #include and typedef changes. |
|
| 1104 |
6630 d 1 h |

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well. |

B+-tree implementation.
Currently supports only inserting and searching. |

Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths. |
