Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.

Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
/kernel/trunk/generic/include/cpu.h
/kernel/trunk/generic/src/time/clock.c
1429

/kernel/trunk/generic/
Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired.
/kernel/trunk/generic/include/ddi/ddi_arg.h
/kernel/trunk/generic/src/ddi/ddi.c
1428

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.

Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
/kernel/trunk/generic/src/mm/backend_anon.c

Update page fault handlers to distinguish between different access modes that had caused the page fault.

/kernel/trunk/arch/mips32/include/mm/page.h

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.

/kernel/trunk/generic/
Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.
/kernel/trunk/generic/include/synch/condvar.h
/kernel/trunk/generic/src/synch/condvar.c

Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount
/kernel/trunk/generic/include/mm/as.h
/kernel/trunk/generic/src/mm/as.c

Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
/kernel/trunk/generic/include/mm/as.h
/kernel/trunk/generic/src/ipc/sysipc.c
/kernel/trunk/generic/src/mm/as.c

/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.
