sys/i386/i386 busdma_machdep.c
Log:
Teach bus_dmamem_free() about contigfree(). This is a bit of a hack,
but it's better than the buggy behavior we have now. If we contigmalloc()
buffers in bus_dmamem_alloc(), then we must configfree() them in
bus_dmamem_free(). Trying to free() them is wrong, and will cause
a panic (at least, it does on the alpha.)
I tripped over this when trying to kldunload my busdma-ified if_rl
driver.
