/kisskb/src/fs/xfs/xfs_inode.c: In function 'xfs_itruncate_extents_flags':
/kisskb/src/fs/xfs/xfs_inode.c:1523:8: warning: unused variable 'done' [-Wunused-variable]
  int   done = 0;
        ^
WARNING: vmlinux.o(.text+0x2fc8): 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.
