 If you have this code compiled into your kernel it will be enabled by default.
 If you want to boot without the bookkeeping anyway you can provide
 'dma_debug=off' as a boot parameter. This will disable DMA-API debugging.
 Notice that you can not enable it again at runtime. You have to reboot to do
 so.
 
-If you want to see debug messages only for a special device driver you can
-specify the dma_debug_driver=<drivername> parameter. This will enable the
-driver filter at boot time. The debug code will only print errors for that
-driver afterwards. This filter can be disabled or changed later using debugfs.

 When the code disables itself at runtime this is most likely because it ran
 out of dma_debug_entries. These entries are preallocated at boot. The number
 of preallocated entries is defined per architecture. If it is too low for you

-As always, this is once again split into "rcu" and "rcu_bh" portions.
-The fields are as follows:
-
-o	"np" is the number of times that __rcu_pending() has been invoked
-	for the corresponding flavor of RCU.
-
-o	"qsp" is the number of times that the RCU was waiting for a
-	quiescent state from this CPU.
-
-o	"cbr" is the number of times that this CPU had RCU callbacks
-	that had passed through a grace period, and were thus ready
-	to be invoked.
-
-o	"cng" is the number of times that this CPU needed another
-	grace period while RCU was idle.
-
-o	"gpc" is the number of times that an old grace period had
-	completed, but this CPU was not yet aware of it.
-
-o	"gps" is the number of times that a new grace period had started,
-	but this CPU was not yet aware of it.
-
-o	"nf" is the number of times that this CPU suspected that the
-	current grace period had run for too long, and thus needed to
-	be forced.
-
-	Please note that "forcing" consists of sending resched IPIs
-	to holdout CPUs.  If that CPU really still is in an old RCU
-	read-side critical section, then we really do have to wait for it.
-	The assumption behing "forcing" is that the CPU is not still in
-	an old RCU read-side critical section, but has not yet responded
-	for some other reason.
-
-o	"nn" is the number of times that this CPU needed nothing.  Alert
-	readers will note that the rcu "nn" number for a given CPU very
-	closely matches the rcu_bh "np" number for that same CPU.  This
-	is due to short-circuit evaluation in rcu_pending().
