Linus,

Please pull the latest objtool/core git tree from:

   # HEAD: 2486baae2cf6df73554144d0a4e40ae8809b54d4 objtool: Allow nested externs to enable BUILD_BUG()

objtool changes for v5.10:

 - Most of the changes are cleanups and reorganization to make the objtool code
   more arch-agnostic. This is in preparation for non-x86 support.

Fixes:

 - KASAN fixes.
 - Handle unreachable trap after call to noreturn functions better.
 - Ignore unreachable fake jumps.
 - Misc smaller fixes & cleanups.

 Thanks,

	Ingo
