powerpc: Reduce printk from pseries_mach_cpu_die()
Remove debug printks in pseries_mach_cpu_die(). These are noisy at runtime. Traceevents can be added to instrument this section of code. The following KERN_INFO printks are removed: cpu 62 (hwid 62) returned from cede. Decrementer value = b2802fff Timebase value = 2fa8f95035f4a cpu 62 (hwid 62) got prodded to go online cpu 58 (hwid 58) ceding for offline with hint 2 Signed-off-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> Cc: Gautham R Shenoy <ego@in.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
