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.

Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.

support for more init tasks
(might break some archs yet)

Support only anonymous address space areas.
1008

Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.

More lightweighed TLB shootdown implementation.

Added simpler userspace starting.
946
6670 d 16 h
jermar

Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.
852
6693 d 0 h
palkovsky
/kernel/trunk/
Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
840

Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
822
6702 d 15 h

Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.

Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.

Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile.

Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.

Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
