Just to clarify -The allocation failure currently happens only on x86_64 - on i386 it uses alloc_bootmem and does not fail. Regardless though this patch is a good idea for both i386 and x86_64 - there is no point in repeatedly allocating memory for large empty strings no matter where it comes from, which was the point of this patch. > > Disadvantage right now: e820 memory allocation currently rounds to pages > always.

I will keep an eye on the ff tree though - when you get to fix it we can switch all early allocs to use it.
