+Subject: x86/asm/32: Fix ANNOTATE_UNRET_SAFE use on 32-bit
+
+From: Jiri Slaby <jslaby@suse.cz>
+
+commit 3131ef39fb03bbde237d0b8260445898f3dfda5b upstream.
+
+The build on x86_32 currently fails after commit
+
+  9bb2ec608a20 (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: 9bb2ec608a20 ("objtool: Update Retpoline validation")
