The first one adds an "append()" helper function for appending to strings, which will also simplify the next patch. The second patch handles "__attribute__((user))" in the field of a trace event. This is needed after the stack leak code added this to parameters of system call events. The last patch adds handling of __builtin_expect(), as someone wanted to move IS_ERR_VALUE() from the fast path into the print fmt section, which breaks the parsing. This should also be useful for other macros that may evaluate down to a __builtin_expect().
