Pull objtool updates from Thomas Gleixner: - Make objtool work for big-endian cross compiles - Make stack tracking via stack pointer memory operations match push/pop semantics to prepare for architectures w/o PUSH/POP instructions. - Add support for analyzing alternatives - Improve retpoline detection and handling - Improve assembly code coverage on x86 - Provide support for inlined stack switching * tag 'objtool-core-2021-02-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) objtool: Support stack-swizzle objtool,x86: Additionally decode: mov %rsp, (%reg) x86/unwind/orc: Change REG_SP_INDIRECT x86/power: Support objtool validation in hibernate_asm_64.S x86/power: Move restore_registers() to top of the file x86/power: Annotate indirect branches as safe x86/acpi: Support objtool validation in wakeup_64.S x86/acpi: Annotate indirect branch as safe x86/ftrace: Support objtool vmlinux.o validation in ftrace_64.S x86/xen/pvh: Annotate indirect branch as safe x86/xen: Support objtool vmlinux.o validation in xen-head.S x86/xen: Support objtool validation in xen-asm.S objtool: Add xen_start_kernel() to noreturn list objtool: Combine UNWIND_HINT_RET_OFFSET and UNWIND_HINT_FUNC objtool: Add asm version of STACK_FRAME_NON_STANDARD objtool: Assume only ELF functions do sibling calls x86/ftrace: Add UNWIND_HINT_FUNC annotation for ftrace_stub objtool: Support retpoline jump detection for vmlinux.o objtool: Fix ".cold" section suffix check for newer versions of GCC objtool: Fix retpoline detection in asm code ...
