1248 6579 d 6 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6580 d 5 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.		  
1238 6580 d 6 h jermar /kernel/trunk/generic/ Rename SYS_AS_AREA_SHARE_APPROVE and SYS_AS_AREA_SHARE_PERFORM, resp., to
SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND, resp. in syscall_t.

Fix prototype of as_area_send() to take only base address of the address
space area as a parameter and read size and flags from the address space
area found at this base address.		  
1236 6580 d 11 h jermar /kernel/trunk/generic/ Add frame_reference_add().  
1235 6580 d 11 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.		  
1233 6582 d 3 h jermar /kernel/trunk/generic/src/mm/ Do not allow zero size address space areas.  
1227 6583 d 7 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1179 6594 d 6 h jermar /kernel/trunk/generic/src/mm/ 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.		  
1178 6594 d 6 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1150 6602 d 14 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 6603 d 1 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6603 d 1 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.		  
1108 6615 d 1 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1076 6620 d 10 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6620 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6621 d 8 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1044 6621 d 10 h jermar /kernel/trunk/ Page table locking.  
1026 6621 d 23 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
983 6623 d 8 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6623 d 8 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
