1417 6568 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.
