Subject: [RFC][PATCH 00/18] objtool/x86: noinstr vs PARAVIRT

Hi!

Per long standing request from Thomas, this here mostly sorts the whole noinstr
validation vs PARAVIRT.

It isn't exactly pretty or robust, but it does work.

So far only tested on x86_64-defconfig+kvm_guest.config+xen.config. I did a
quick allyesconfig build, but still saw some funnies with that, will poke at them.
