x86: unify PM-Timer messages
Impact: Cleans up printk formatting When LOCAL APIC was calibrated, the debug message is displayed as follows. CPU0: Intel(R) Xeon(R) CPU 5110 @ 1.60GHz stepping 06 Using local APIC timer interrupts. calibrating APIC timer ... ... lapic delta = 3773131 ... PM timer delta = 812434 APIC calibration not consistent with PM Timer: 226ms instead of 100ms APIC delta adjusted to PM-Timer: 1662420 (3773131) TSC delta adjusted to PM-Timer: 159592409 (362220564) ..... delta 1662420 ..... mult: 71411249 ..... calibration result: 265987 ..... CPU clock speed is 1595.0924 MHz. ..... host bus clock speed is 265.0987 MHz. There are three type of PM-Timer (PM-Timer, PM Timer, and PM timer), in this message. This patch unifies those messages to PM-Timer. Signed-off-by: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
