You still need that NEXT_PAGE(level1_fixmap_pgt) thing: arch/x86/kernel/head_64.o: In function `level2_fixmap_pgt': (.data+0x2fd0): undefined reference to `level1_fixmap_pgt'
Yes, I said it wasn't a complete patch. There are bits missing, and some of them need restructuring. The ident page table in the trampoline should be handled by mirroring the kernel ident page tables instead, for example -- right now that is completely broken if the kernel lives above the 512 GiB mark.
