Hi Fengguang,
I occasionally get compilation bug reports from people who are
cross-compiling an x86-64 kernel target on an x86-32 host.
Any chance the 0-day build bot could test that configuration? I think
just building a defconfig would be sufficient. It would help sort out
issues in objtool and other host-built scripts.

To do that we'll need to create a new build chroot. Julie/Philip
should be able to evaluate the efforts and do the plan.
Thanks,

got it, we will consider this in future plan after some evaluation.
