All warnings (new ones prefixed by >>, old ones prefixed by <<):

WARNING: modpost: EXPORT symbol "ethtool_set_ethtool_phy_ops" version generation failed, symbol will not be versioned.
>> WARNING: modpost: vmlinux.o(.text.unlikely+0x11494): Section mismatch in reference from the function bcm2836_arm_irqchip_smp_init() to the function .init.text:set_smp_ipi_range()
The function bcm2836_arm_irqchip_smp_init() references
the function __init set_smp_ipi_range().
This is often because bcm2836_arm_irqchip_smp_init lacks a __init
annotation or the annotation of set_smp_ipi_range is wrong.
