Patch to fix panic when a bounce buffer is needed.
In lib/swiotbl.c, an attempt to use a DMA buffer outside the limits allowed by
the b44 hardware (30 bits), the kernel panics rather than returning an error.
Code in b44 is prepared to handle this condition using a bounce buffer.
This bug was fixed in mainline with commit fba99fa, which was marked with a Cc:
for stable. It was incorporated in 2.6.37.2, but that fix has not yet been
propagated to the openSUSE 11.4 kernel.
