The USB hid implementation does retrieve the reports during the start.
However, this implementation does not call the HID command GET_REPORT
(which would fetch the current status of each report), but use the
DATA command, which is an Output Report (so transmitting data from the
host to the device).
The Wiimote controller is already guarded against this problem in the
protocol, but it is not conformant to the specification to set all the
reports to 0 on start.

bgmac uses bcm47xx_nvram.h which is only available when BCM47XX was

build on any other archs, but that changed. We should modify this

mm/slab: Fix drain freelist excessively
slob: Rework #ifdeffery in slab.h
mm, slab: moved kmem_cache_alloc_node comment to correct place
Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)
Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.
As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?
