Can you please comment on the effect of using or not using
LLVM/Clang's IA (integrated assembler)?

What effect has '-no-integrated-as' when set as a compiler-flag in
general and in case of this issue?

Do you (exclusively) use IA for compiling your Linux x86_64 kernels?
You had success?
Do you use also '-no-integrated-as' as compiler-flag in your build?
Which Linux-kernel version was known to be buildable and/or bootable?
Which llvmlinux-patches for x86_64 did you have in your series (a
complete list, please)?

Lots of questions.
