+Subject: x86/asm/32: Make sync_core() handle missing CPUID on all 32-bit kernels
+
+From: Andy Lutomirski <luto@kernel.org>
+
+commit 1c52d859cb2d417e7216d3e56bb7fea88444cec9 upstream.
+
+We support various non-Intel CPUs that don't have the CPUID
+instruction, so the M486 test was wrong.  For now, fix it with a big
+hammer: handle missing CPUID on all 32-bit CPUs.
