Just curious, is there a reason for the RELOC_HIDE() here? Or
__pa_symbol() for that matter? It looks like only x86 uses this on the
__nosave_{begin,end} symbol. Maybe it's copy-pasta?
I also wonder if anyone has thought about making a __weak
pfn_is_nosave() function so that architectures don't need to implement
the same thing every time. Consolidating those shouldn't be part of this
patch though.
