[Qemu-devel] sparc dma length bug(and fix) seen with NetBSD

Using QEMU 0.9.1 for sparc emulation, a dma length bug is seen with NetBSD.
When an 8192 byte block is read to memory using dma into non-contiguous
memory, the 2nd 4k block of contiguous memory is also written to.
This is due to an incorrect variable being used for length.
See the attached patch. I see the same bug on subversion trunk.
