[PATCH] x86: Update cbmem driver

[Alex Sadovsky]

Dear Simon and other developers,

While at it, is it OK to increment cons->cursor unconditionally,
even when the buffer is full?

It's better to do it after the check, isn't it? E.g.:

	if (cons->cursor < cons->size)
		cons->body[cons->cursor++] = data;

Cheers, Alex.
