I think __weak functions are too fragile, when you do this and it turns out that another architecture does need to do something, you won't ever get any indication of it.

If we know that arm64 doesn't need to do anything here, just add an arch/arm64/include/asm/kaslr.h with an empty function there.

I'm looking at fs/proc/vmcore.c and all those other weak functions there and just doing the same.

Also, judging by

$ git grep CONFIG_PROC_VMCORE

output, ia64, mips and powerpc would need that include too.
