KERN_PCI
KERN_ACPI
v4: fix some checkpatch error and warning
v5: add default with DEFINE_LOGLEVE_SETUP_DEF
KERN_APIC
v6: set the default only one time
v7: expand msg_loglevel to 2 digi bits. so KERN_APIC could start from 10

usage:
in .h to have
#define KERN_PCI "<pci>"
in .c to have
DEFINE_LOGLEVEL_SETUP(pci, KERN_PCI, "pci:");
then could use
printk(KERN_DEBUG KERN_PCI fmt, ...);
and command line
loglevel=3,pci:8

you can add different printk to different files of one subsys if you like
not just one susbsys one tag, and don't need to update kernel.h to add more tags
