Subject: printks messed up in 3.6-rc2+git

1. Lots of broken HPET messages scattered in PCI prontks like this:
pcieport 0000:00:0c.0: Force enabled HPET at 0x%lx
irq 40 for MSI/MSI-X
pcieport 0000:00:0d.0: Force enabled HPET at 0x%lx
irq 41 for MSI/MSI-X
pcieport 0000:00:0e.0: Force enabled HPET at 0x%lx
irq 42 for MSI/MSI-X
pcieport 0000:00:0f.0: Force enabled HPET at 0x%lx
irq 43 for MSI/MSI-X

2. Lots of \0x10 in different printk lines, like this:

pci 0000:00:05.0: \x010Enabling HT MSI Mapping
pci 0000:00:05.1: \x010Enabling HT MSI Mapping
pci 0000:00:05.2: \x010Enabling HT MSI Mapping
pci 0000:00:06.0: \x010Enabling HT MSI Mapping
pci 0000:00:06.1: \x010Enabling HT MSI Mapping
pci 0000:00:08.0: \x010Enabling HT MSI Mapping
pci 0000:00:09.0: \x010Enabling HT MSI Mapping
pci 0000:00:0c.0: \x010Enabling HT MSI Mapping
pci 0000:00:0d.0: \x010Enabling HT MSI Mapping
pci 0000:00:0e.0: \x010Enabling HT MSI Mapping
pci 0000:00:0f.0: \x010Enabling HT MSI Mapping
and this:
usb 2-8: \x010new low-speed USB device number 5 using ohci_hcd
usb 2-8: \x010New USB device found, idVendor=0592, idProduct=0002
usb 2-8: \x010New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 2-8: %s: Can't disable non-U1 or U2 state.

3. Many more %s and runtogether lines:

sata_nv 0000:00:05.1: %s: ino %lu, used %d with only %d reserved data blocksUsing SWNCQ mode

[ 15.379760] usb 1-1.2.3: mminit::memmap_init Initialising map node
%d zone %lu pfns %lu -> %lu
[ 15.379760] default language 0x0409

[ 15.393768] udev 6, busnum 1, minor = 5
[ 15.407012] usb 1-1.2.3: Oops - undefined instructionNew USB device
found, idVendor=0cf3, idProduct=9271
[ 15.417175] usb 1-1.2.3: Oops - undefined instructionNew USB device
