+Subject: x86/static-call: fix 32-bit build
+
+From: Juergen Gross <jgross@suse.com>
+
+commit 349f0086ba8b2a169877d21ff15a4d9da3a60054 upstream.
+
+In 32-bit x86 builds CONFIG_STATIC_CALL_INLINE isn't set, leading to
+static_call_initialized not being available.
+
+Define it as "0" in that case.
+
+Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
+Fixes: 0ef8047b737d ("x86/static-call: provide a way to do very early static-call updates")
