1780 6751 d 11 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6762 d 13 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1757 6765 d 16 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6767 d 18 h decky /kernel/trunk/ make kernel prints case consistent  
1705 6771 d 17 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6772 d 14 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1594 6780 d 4 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1587 6780 d 11 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.		  
1544 6782 d 15 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1495 6784 d 4 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1483 6784 d 15 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 6785 d 12 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1461 6785 d 15 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1437 6788 d 8 h jermar /kernel/trunk/generic/src/mm/ Fix used_space_insert() to correctly service an empty used_space B+tree.  
1436 6788 d 9 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 6788 d 10 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1428 6789 d 6 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.		  
1424 6789 d 11 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 6789 d 15 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6791 d 7 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.
