Linus,

Please pull the latest objtool/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 
objtool-core-2020-10-13

   # HEAD: ab0a40ea88204e1291b56da8128e2845fec8ee88 perf build: Allow nested 
externs to enable BUILD_BUG() usage

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
