--------------------------------

commit 3131ef39 upstream.

The build on x86_32 currently fails after commit

  9bb2ec60 (objtool: Update Retpoline validation)

with:

  arch/x86/kernel/../../x86/xen/xen-head.S:35: Error: no such instruction: `annotate_unret_safe'

ANNOTATE_UNRET_SAFE is defined in nospec-branch.h. And head_32.S is
missing this include. Fix this.

Fixes: 9bb2ec60 ("objtool: Update Retpoline validation")
