Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 - Fix obtaining the 'start' address for a kernel module on s390, where
   .text doesn't coincide with the start of the module as reported in
   /proc/modules (Song Shan Gong)

 - Use official ELF e_machine value for BPF objects generated via perf + LLVM
   when specifying BPF scriptlet in 'perf record/trace --event' (Wang Nan)
