/kernel/trunk/
Cleanup pm.c and pm.h code on ia32 and amd64.

Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.

Add some sanity checks to make sure the address space created by SYS_MAM_PHYSMEM will not be remapped
and that as_page_fault() will not try to service page fault for that area.

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

Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.
1153

/kernel/trunk/generic/src/synch/
Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too.
1150

/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.
1144

/kernel/trunk/
Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.
1142
6751 d 14 h
jermar
/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/src/ipc/
Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.

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.

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().

Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).
1134
6758 d 9 h
jermar
/kernel/trunk/generic/src/adt/
Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node

Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.
