Linus Torvalds a56ff24efb objtool updates:
- Make objtool work for big-endian cross compiles
 
  - Make stack tracking via stack pointer memory operations match push/pop
    semantics to prepare for architectures w/o PUSH/POP instructions.
 
  - Add support for analyzing alternatives
 
  - Improve retpoline detection and handling
 
  - Improve assembly code coverage on x86
 
  - Provide support for inlined stack switching
