WARNING: vmlinux.o(.cpuinit.text+0x3cc4): Section mismatch in reference from the function uv_cpu_init() to the function .init.text:uv_system_init() The function __cpuinit uv_cpu_init() references a function __init uv_system_init(). If uv_system_init is only used by uv_cpu_init then annotate uv_system_init with a matching annotation. uv_system_init was ment to be called only once, so do it from codepath (native_smp_prepare_cpus) which is called once, right before activation of other cpus (smp_init). Note: old code relied on uv_node_to_blade being initialized to 0, but it'a not initialized from anywhere.
