History
Linus Torvalds 857f1268a5 Changes in this cycle were: 
- Shrink 'struct instruction', to improve objtool performance & memory
    footprint.
 
  - Other maximum memory usage reductions - this makes the build both faster,
    and fixes kernel build OOM failures on allyesconfig and similar configs
    when they try to build the final (large) vmlinux.o.
 
  - Fix ORC unwinding when a kprobe (INT3) is set on a stack-modifying
    single-byte instruction (PUSH/POP or LEAVE). This requires the
    extension of the ORC metadata structure with a 'signal' field.
 
  - Misc fixes & cleanups.
