problem:
I see sometimes on my mpc5200 based board such printk timing
information:
[ 0.000000] NR_IRQS:512 nr_irqs:512 16
[ 0.000000] MPC52xx PIC is up and running!
[ 0.000000] clocksource: timebase mult[79364d9] shift[22] registered
[ 0.000000] console [ttyPSC0] enabled
[ 130.300633] pid_max: default: 32768 minimum: 301
[ 130.305647] Mount-cache hash table entries: 512
[ 130.315818] NET: Registered protocol family 16
reason:
if the tbu not starts from 0 when linux boots, boot_tb
maybe could not store the real 64 bit tbu value, because
boot_tp is only a 32 bit unsigned long.
solution:
change boot_tb to u64
[BenH: Made it u64 instead of unsigned long long]
