Hi, Any progress/update with this patch ? Please do let know, if something more is needed here.

That seems like a bug, not a warning. Have you looked at why we're seeing this warning? It seems like maybe something else is going wrong to get us into this situation to begin with. If there's some good reason why this is happening, and it's truly harmless, then we can just remove the printk() entirely. cheers

printk() in unmap_cpu_from_node() uses KERN_ERR message severity, for a WARNING message. Change it to pr_warn(). Signed-off-by: Vipin K Parashar <vipin@linux.vnet.ibm.com> --- arch/powerpc/mm/numa.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
