1544 6735 d 4 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6735 d 10 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1495 6736 d 17 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1483 6737 d 4 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1468 6738 d 2 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1461 6738 d 4 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1437 6740 d 21 h jermar /kernel/trunk/generic/src/mm/ Fix used_space_insert() to correctly service an empty used_space B+tree.  
1436 6740 d 22 h jermar /kernel/trunk/generic/src/mm/ Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c.  
1434 6741 d 0 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1428 6741 d 19 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.		  
1426 6741 d 20 h jermar /kernel/trunk/generic/src/mm/ Support for sharing address space areas backed up by ELF image.  
1425 6741 d 22 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6742 d 0 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.		  
1423 6742 d 4 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6743 d 21 h jermar /kernel/trunk/generic/ Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.

The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.		  
1415 6744 d 9 h jermar /kernel/trunk/generic/ Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount		  
1413 6744 d 20 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1411 6745 d 1 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1409 6745 d 19 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1403 6747 d 8 h jermar /kernel/trunk/generic/src/mm/ Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes.
