1235 6595 d 3 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 6596 d 19 h jermar /kernel/trunk/generic/src/mm/ Do not allow zero size address space areas.  
1227 6597 d 23 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 6608 d 22 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 6608 d 22 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1150 6617 d 6 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 6617 d 17 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6617 d 17 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 6629 d 17 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1076 6635 d 2 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6635 d 5 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6636 d 0 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 6636 d 2 h jermar /kernel/trunk/ Page table locking.  
1026 6636 d 15 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
983 6638 d 0 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6638 d 0 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6638 d 1 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6638 d 3 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
840 6665 d 1 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
823 6671 d 15 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
