Modified files:
sys/sparc64/include frame.h pcb.h
sys/sparc64/sparc64 exception.s
Log:
Add support for splitting the register windows on entry to the
kernel from usermode. The remaining user windows are spilled
to the pcb as necessary. The user land window fault handlers
fill directly from the pcb on return.
Add system call entry points.
