virtio-console.c used to return a value less than the number of bytes
asked to be written out to a chardev backend in case the backend is not
writable.  virtio-serial-bus.c then implicitly enabled flow control for
that port.

Make this explicit instead.

The BIT6 of Status Register(SR):

SR[6] behaves the same as R/B# pin
    SR[6] = 0 indicates the device is busy;
    SR[6] = 1 means the device is ready

Some NAND flash controller (i.e. ftnandc021) relies on the SR[6]
to determine if the NAND flash erase/program is success or error timeout.

P.S:

When using an in-kernel GIC with KVM, we need to tell the kernel where

when the GIC is actually mapped.
