Though I do not know much about -mno-explicit-relocs,
CONFIG_BUILD_ELF64 controls -msym32 option and this is the reason of
the tweak in __pa_page_offset().

I thought -msym32 can not be used for 64-bit kernels which do not have
CKSEG load address, but apparently IP27 is using -msym32 with XKPHYS
load address.  Hmm...
