I started to see these messages in January (around Linux 3.2.0), but never
investigated what it was since the produced kernels continued to boot just
fine.
The above change was added by me. The message is printed when the 'wrapper'
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?
the right spot without printing a message?
