Hi,
we use on PPCs __asm__ volatile ("eieio"), which is the correct
assembler instruction to make sure that the write has finished before
the next read on VMEbus is executed.
The same by the way is true for 68k archticture where the instruction
would be "nop".
On Intel cpus I don't know how to solve this, maybe a few useless
instructions will do.
