Subject: [GIT PULL] objtool updates for v5.13

Linus,

Please pull the latest objtool/core git tree from:

   # HEAD: 7d3d10e0e85fb7c23a86a70f795b1eabd2bc030b x86/crypto: Enable objtool in crypto code

Objtool updates in this cycle were:

 - Standardize the crypto asm code so that it looks like compiler-generated
   code to objtool - so that it can understand it. This enables unwinding
   from crypto asm code - and also fixes the last known remaining objtool
   warnings for LTO and more.

 - x86 decoder fixes: clean up and fix the decoder, and also extend it a bit

 - Misc fixes and cleanups

 Thanks,

	Ingo
