But restore_pblist == 0xffff800971b7f998 when passed to __phys_addr_symbol().

This change causes resume from hibernate to panic in:

It looks like kaslr's relocation code has already fixed restore_pblist, so your
debug virtual check catches this doing the wrong thing. My bug.

But restore_pblist == 0xffff800971b7f998 when passed to __phys_addr_symbol().
