These two patches allow to batch writes to MMIO.
When kernel has to send MMIO writes to userspace, it stores them
in memory until it has to pass the hand to userspace for another
reason. This avoids to have too many context switches on operations
that can wait.
WARNING: this breaks compatibility with old userspace part.
