Though the names are different, their corresponding values are exactly same. The former is used by EEH core and the latter is used by userspace. The patch moves those constants from arch/powerpc/include/asm/eeh.h to arch/powerpc/include/uapi/asm/eeh.h, which are expected to be used by userspace from now on. We can't delete those constants in vfio.h as it's uncertain that those constants have been or will be used by userspace.
