1380 6560 d 0 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1358 6564 d 3 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1329 6566 d 2 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1306 6569 d 4 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.		  
1288 6575 d 8 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1239 6584 d 2 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 6584 d 3 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.		  
1235 6584 d 8 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.		  
1227 6587 d 3 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.		  
1178 6598 d 3 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1149 6606 d 21 h jermar /kernel/trunk/generic/include/mm/ s/B+-tree/B+tree/  
1147 6606 d 21 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.		  
1070 6624 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6625 d 5 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 6625 d 7 h jermar /kernel/trunk/ Page table locking.  
1026 6625 d 20 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
977 6627 d 5 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6627 d 7 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
940 6629 d 1 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
823 6660 d 20 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
