commit 11a62a056093a7f25f1595fbd8bd5f93559572b6 turns some formerly nopped
debugging printks in arch/x86/kernel/mppparse.c into regular ones. The
one at the top of smp_scan_config() in particular also prints on
!CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines without anything
resembling MP tables which makes their lowly UP owners wonder...

Given that it was up to this point also not considered valuable user-level
information, let's just kill that one.

why? that just three lines debug debug info.
For the reasons described in the changelog text. They look quite valid
to me.

then how about system do have mptable ?

Those print:

printk(KERN_INFO "found SMP MP-table at [%p] %08lx\n",
mpf, virt_to_phys(mpf));

a few lines down. Note moreover that is used to be a "Dprintk()" which was defined to <nop> before -- ie, no change.
