Subject[RFC PATCH v3 00/12] objtool: Enable and implement --mcount option on powerpc
Date
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
