It was being defined as the constant 64 and at first I changed it to be NR_CPUS instead. However, NR_CPUS can be a large value on recent kernels (4096), and this may cause too large kmem allocations to happen. Therefore, now we use num_possible_cpus(), which should return a (typically) small value which represents the maximum number of CPUs than can be brought online in the running hardware (this value is determined at boot time by arch-specific kernel code).

The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.
Documentation for building, configuring, and using the SPL can be found at: http://wiki.github.com/behlendorf/spl/
