powerpc: Fix objtool unannotated intra-function call warnings on PPC32
Sathvika Vasireddy (12):
powerpc: Replace unreachable() with it's builtin variant in WARN_ON()
powerpc: override __ALIGN() and __ALIGN_STR() macros
powerpc: Fix objtool unannotated intra-function call warnings
powerpc: curb objtool unannotated intra-function call warnings
powerpc: Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o
powerpc: Skip objtool from running on VDSO files
objtool: Add --mnop as an option to --mcount
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
