[PATCH 1/2] tools/stacktool: Add __reiserfs_panic to global_noreturns list

From: Chris J Arges
Date: Fri Jan 22 2016 - 16:45:45 EST

The following false positives were noticed with stacktool:
stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x9e: return without frame pointer restore
stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x89: duplicate frame pointer save
stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x8a: duplicate frame pointer setup
stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x9e: frame pointer state mismatch
stacktool: fs/reiserfs/namei.o: set_de_name_and_namelen()+0x0: frame pointer state mismatch

These all call into '__reiserfs_panic' which has a noreturn attribute. Add this
to the global list because this particular attribute cannot be determined from
reading the ELF object.
