This patchset drop the approach of creating new stub type for livepatch symbols and offloads the issue of handling local function becoming global to kpatch tool via gcc-plugin. In function restore_r2(), a check for sibling call is added and also improves the error message on unexpected op-code. v4: - Drop creation of stubs for livepatch symbols and offload solution to kpatch tool. - Introduce check for sibling call, when restoring r2 after branch. (Josh) - Improve error message in restore_r2(). (Josh) v3: - Defined FUNC_DESC_OFFSET to calculate func_desc offset from struct ppc64le_klp_stub_entry. - Replaced BUG_ON() with WARN_ON() in klp_stub_for_addr(). - Major commit message re-write. v2: - Changed klp_stub construction to re-use livepatch_handler and additional patch code required for klp_stub, instead of duplicating it. - Minor comments and commit body edit.
