Modified Files:
src/sys/arch/next68k/include: bus_space.h
Log Message:
next68k: Specify proper constraints for bus_space_read region and multi ops.
These functions write the read data into memory at a specified pointer,
but without the "memory" constraint gcc could optimize out these ops
if the memory is allocated on local stack.
With this fix nextkbd(4) works again.
Should be pulled up to netbsd-10 and netbsd-9.
