These patches are rebased on top of objtool/core
branch of the tip tree, and are tested on
ppc64le with ppc64le_defconfig.

Christophe Leroy (3):
  objtool: Fix SEGFAULT
  objtool: Use target file endianness instead of a compiled constant
  objtool: Use target file class size instead of a compiled constant

Sathvika Vasireddy(9):
  objtool: Add --mnop as an option to --mcount
  powerpc: Skip objtool from running on VDSO files
  objtool: Read special sections with alts only when specific options are selected
  objtool: Use macros to define arch specific reloc types
  objtool: Add arch specific function arch_ftrace_match()
  objtool/powerpc: Enable objtool to be built on ppc
  objtool/powerpc: Add --mcount specific implementation
  powerpc: Remove unreachable() from WARN_ON()
  objtool/powerpc: Fix unannotated intra-function call warnings
