This patch set reorganize current x86 related code in objtool, [1-3] move arch-specific to arch files and extract some common codes, [4] fixes a cross-compile problem and [5] fixes a call destination search bug.
It make objtool more arch-generic, which makes other patches on different architectures easier to be reviewed and merged.
Tested on x86 with unwind on kernel and module context.
--- v2 Change: [5/5] objtool: use arch_jump_destination in read_intra_function_calls --- Chen Zhongjin (3): objtool: Add generic symbol for relocation type objtool: Specify host-arch for making LIBSUBCMD objtool: use arch_jump_destination in read_intra_function_calls
Madhavan T. Venkataraman (2): objtool: Make ORC type code arch-specific objtool: Make ORC init and lookup code arch-generic
