Revision 0032c857454581510de1ca12615de5e38e543c92 authored by David S. Miller on 03 December 2012, 19:24:25 UTC, committed by David S. Miller on 03 December 2012, 19:24:25 UTC
Newer versions of binutils mark '_end' as 'B' instead of 'A' for
whatever reason.

To be honest, the piggyback code doesn't actually care what kind
of symbol _start and _end are, it just wants to find them and
record the address.

So remove the type from the match strings.
