Brian Behlendorf 33a19e0fd9 Fix kernel unaligned access on sparc64
Update the SA_COPY_DATA macro to check if architecture supports
efficient unaligned memory accesses at compile time.  Otherwise
fallback to using the sa_copy_data() function.

The kernel provided CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is
used to determine availability in kernel space.  In user space
the x86_64, x86, powerpc, and sometimes arm architectures will
define the HAVE_EFFICIENT_UNALIGNED_ACCESS macro.
