[akpm]

The patch titled
     Subject: scripts/decode_stacktrace.sh: skip missing symbols
has been removed from the -mm tree.  Its filename was
     scripts-decode_stacktrace-skip-missing-symbols.patch

------------------------------------------------------
From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru>
Subject: scripts/decode_stacktrace.sh: skip missing symbols

For now script turns missing symbols into '0' and make bogus decode.  Skip
them instead.  Also simplify parsing output of 'nm'.

Before:

$ echo 'xxx+0x0/0x0' | ./scripts/decode_stacktrace.sh vmlinux ""
xxx (home/khlebnikov/src/linux/./arch/x86/include/asm/processor.h:398)

After:

$ echo 'xxx+0x0/0x0' | ./scripts/decode_stacktrace.sh vmlinux ""
xxx+0x0/0x0
