CONFIG_64BIT=y
# CONFIG_X86_32 is not set
CONFIG_X86_64=y
CONFIG_X86=y

it is 64bit, so something wrong with

+static int __devinit
+wakeup_secondary_cpu(int apicid, unsigned long start_eip)
+{
+	if (x86_quirks->wakeup_secondary_cpu)
+		return x86_quirks->wakeup_secondary_cpu(apicid, start_eip);
+
+	return wakeup_secondary_cpu_via_init(apicid, start_eip);
+}

x86_quirks->wakeup_secondary_cpu get assigned when es7000 with CLUSTERED (_MIP) or numaq  with _nmi

it's werid.

timing issue?
