Yes. We had it before for __supported_pte_mask and other users of
fixup_pointer().

See for instance 4a09f0210c8b ("x86/boot/64/clang: Use fixup_pointer() to
access '__supported_pte_mask'")

Unless we find other way to guarantee RIP-relative access, we must use
fixup_pointer() to access any global variables.
