Not sure if this is related, but at the end of each kernel compilation,
the following messages are printed:

I started to see these messages in January (around Linux 3.2.0), but nev=

investigated what it was since the produced kernels continued to boot ju=

fine.

The above change was added by me. The message is printed when the 'wrappe=

r'

script finds that decompressed kernel overlaps the 'bootstrap code' which
does the decompression. So it shifts the 'address' of the bootstrap code =

to

the next higher MB. As such it is harmless.

I see this message every time when I build the kernel.  I know it's
harmless, but is this something that can be "fixed"?  That is, can we
change some linker script (or whatever) to make 0x700000 the default
value?  Or maybe modify the wrapper script to just automatically find
the right spot without printing a message?
