relocatable modules' symbols

[horseriver]

hi:

  I have built vmlinux at the top dir of kernel source ,then I use objdump to look into
  its section information.I find the statup_32 which is the start routine of kernel ,
  locats at 0xc0100000. I know the 0x100000 is the defined address for locating 
  protect-mode code .But which I can not understand is the 0xc prefix .where does it come from?

thanks!
