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
