I got it to compile now with this patch (+ one additional patch
that is folded in). It then goes through kernel initialization
and then init gets killed with "Inconsistency detected by rtld.c:1250:
Assertation ph_vaddr == _rtld_local.dl_sysinfo_vdso failed"
It looks like some of the ifdefs were placed completely wrong
and in addition you were missing a patch to include asm/offset.h
everywhere as assembly (I patched around that). And two macros
were apparently never compiled in their current form.
But it seems it is dependent on even more -mm* magic than just
that. If you can identify the missing patches that make init's
rtld work again that would be useful.

Get paravirt ops to compile
TBD should be folded into the original patches
Unfortunately still doesn't boot.
