1262 6763 d 11 h jermar /kernel/trunk/generic/src/adt/ Fix a bug caused by an unsigned subtraction of bigger value from smaller value in bitmap implementation.
Fix wrong calculation of unaligned leading bits in bitmap implementation.		  
1248 6766 d 13 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6771 d 8 h decky /kernel/trunk/ printf-related and other code cleanup  
1200 6776 d 15 h jermar /kernel/trunk/ Add bitmap ADT.  
1196 6777 d 17 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6781 d 18 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6784 d 14 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1154 6788 d 13 h jermar /kernel/trunk/generic/src/adt/ Fix critical bug in hash table initialization.
Only half of the table was actually allocated and initialized.		  
1150 6789 d 21 h jermar /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.		  
1148 6790 d 8 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6790 d 8 h jermar /kernel/trunk/generic/ 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 6792 d 12 h jermar /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 6792 d 20 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.)		  
1140 6794 d 12 h jermar /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.		  
1136 6798 d 11 h jermar /kernel/trunk/generic/src/adt/ 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 6799 d 15 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		  
1121 6801 d 9 h jermar /kernel/trunk/ Small textual changes.  
1101 6804 d 10 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.		  
902 6823 d 18 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
822 6844 d 8 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
