[PATCH] powerpc/configs/64s: Enable CONFIG_PRINTK_CALLER

2020-05-20 Thread Michael Ellerman 
This adds the CPU or thread number to printk messages. This helps a
lot when deciphering concurrent oopses that have been interleaved.

Example output, of PID1 (T1) triggering a warning:

  [1.581678][T1] WARNING: CPU: 0 PID: 1 at crypto/rsa-pkcs1pad.c:539 
pkcs1pad_verify+0x38/0x140
