Hengqi Chen c3597996a3 LoongArch: Preserve syscall nr across execve() ... [ Upstream commit d6c5f06e46 ] Currently, we store syscall nr in pt_regs::regs[11] and syscall execve() accidentally overrides it during its execution: sys_execve() -> do_execve() -> do_execveat_common() -> bprm_execve() -> exec_binprm() -> search_binary_handler() -> load_elf_binary() -> ELF_PLAT_INIT() ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode() we later get a wrong syscall nr. This breaks tools like execsnoop since it relies on execve() tracepoints. Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.
