Currently zram allocates 2 physically contiguous pages per-CPU's compression stream (we may have up to 4 streams per-CPU). Since those buffers are per-CPU we allocate them from CPU hotplug path, which may have higher risks of failed allocations on devices with fragmented memory. Switch to virtually contiguous allocations - crypto comp does not seem impose requirements on compression working buffers to be physically contiguous.
