 434  * the initial JUMP).
 435  *
 436  * This is the risc program of the first buffer to be queued if the active list

 438  * interrupts.
 439  *
 440  * If a new buffer is added then the initial JUMP in the code for that buffer
 441  * will generate an interrupt which signals that the previous buffer has been
 442  * DMAed successfully and that it can be returned to userspace.
 443  *
 444  * It also sets the final jump of the previous buffer to the start of the new
 445  * buffer, thus chaining the new buffer into the DMA chain. This is a single
 446  * atomic u32 write, so there is no race condition.
 447  *
