On PowerPC, when dymically removing memory from a system we can see in the console a
lot of messages like this:
[ 186.575389] Offlined Pages 4096
Is it specific to PowerPC ?
No, this applies to all architectures, but this is surfacing a bit more on
PowerPC where the memory block size is set to 256MB currently by the firmware.
This message is displayed on each LMB (256MB) removed, which means that we
removing 1TB of memory, this message is displayed 4096 times.
Moving it to DEBUG to not flood the console.
