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

>> WARNING: modpost: vmlinux.o(.text+0xb1ae): Section mismatch in reference from the function pt_ops_set_early() to the function .init.text:alloc_pte_early()
The function pt_ops_set_early() references
the function __init alloc_pte_early().
This is often because pt_ops_set_early lacks a __init
annotation or the annotation of alloc_pte_early is wrong.
