  "message": "[POWERPC] Document when printk is useable\n\nWhen debugging early boot problems, it\u0027s common to sprinkle printk\u0027s\nall over the place.  However, on 64-bit powerpc, this can lead to\nmemory corruption if done too early due to the PACA pointer and\nlockdep core not being initialized.\n\nThis adds some comments to early_setup() that document when it is\nsafe to do so in order to save time for whoever has to debug that\nstuff next.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n",
