[PATCH] patch to buffer write ioreq
This patch implements a new mechanism to buffer the MMIO_WRITE and
PIO_WRITE packet in a queue, and then submit them to qemu-dm in batch.
This could save a lot of domain switch time. We implement this as a
generic one to do ioreq in batch. However, we only use it to batch the
MMIO_WIRTE request for stdvga(0xA0000-0xC0000) in order to solve the
win2k boot issue for hvm domain.
Without this patch, win2k cannot boot up on HVM domain.
