/kisskb/src/kernel/futex.c:1674:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized]

WARNING: vmlinux.o(.text+0x2fd0): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
