UBUNTU: abi-check -- be more forgiving of the ABI element type
BugLink: http://bugs.launchpad.net/bugs/576274
With some configurations we may find entries in the ABI which are not
EXPORT_*. For example with CONFIG_UNUSED_SYMBOLS=n entries marked as
UNUSED are listed as below:
(unknown) vmlinux 0xc48a85c4 simple_prepare_write
This leads to an undiagnosable error from abi-check:
Missing module name in is_ignored() at debian/scripts/abi-check line 77.
There is no obvious reason to limit ourselves to EXPORT_* in the abi files.
Separatly we should ensure that CONFIG_UNUSED_SYMBOLS is set.
