I discovered this deadlock condition awhile ago working on RAMster but it affects zcache as well. The list spinlock must be locked prior to the page spinlock and released after. As a result, the page copy must also be done while the locks are held. Applies to 3.2. Konrad, please push (via GregKH?)... this is definitely a bug fix so need not be pushed during a -rc0 window.
