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

>> WARNING: modpost: vmlinux.o(.text+0xd0c889): Section mismatch in reference from the function exynos_pcie_probe() to the function .init.text:exynos_add_pcie_port()
The function exynos_pcie_probe() references
the function __init exynos_add_pcie_port().
This is often because exynos_pcie_probe lacks a __init
annotation or the annotation of exynos_add_pcie_port is wrong.
