I get lots of this when building latest -mm for avr32:

.tmp_kallsyms2.S:643: Warning: right operand is a bignum; integer 0
assumed

Reverting this patch makes the warnings go away. I think it's
because on avr32, .init is the first section, not .text, so many of the
offsets become negative and kallsyms doesn't seem to handle this very
well. Here's a few lines from .tmp_kallsyms2.S:

kallsyms_addresses:
PTR _text + 0xffffffffffff4000
PTR _text + 0xffffffffffff4000

Any idea how to fix this? Could we introduce a new symbol that always
marks the start of the image perhaps?


Maybe we should generate it as a signed value (-0x8000) instead of an unsigned value.
