A 2 line printk makes dmesg output messy, because the second line does not get
a timestamp.
For example:
[ 0.012863] CPU0: Thermal monitoring enabled (TM1)
[ 0.012869] Last level iTLB entries: 4KB 1024, 2MB 1024, 4MB 1024
Last level dTLB entries: 4KB 1024, 2MB 1024, 4MB 1024, 1GB 4
[ 0.012958] Freeing SMP alternatives memory: 28K (ffffffff81d86000 -
ffffffff81d8d000)
[ 0.014961] dmar: Host address width 39
V2: Revert change to log level, only fix the newline formatting issue
