Clang's integrated assembler only supports UAL and rejects instructions that are UNPREDICTABLE; KernelCI has been warning about those for awhile now when using GAS (GCC or Clang) for allmodconfig builds.
Changes V4 -> V5: * Make patch into series. * Fix the UNPREDICTABLE warnings first. * Add .syntax unified to fix the GCC build failure reported by 0day bot. Changes V3 -> V4: * use __inst_arm for movs based on resolution of https://reviews.llvm.org/D95586. Changes V2 -> V3: * drop changes to test-thumb.c. That file is mutually exclusive with test-arm.c based on CONFIG_THUMB2_KERNEL. LLVM requires more fixes for .w suffixes for thumb2 mode. Changes V1 -> V2: * Fix additonal swpvsb case in test-arm.c when __LINUX_ARM_ARCH__ < 6, reported by Arnd. * Fix arch/arm/probes/kprobes/test-thumb.c, reported by Arnd. * Modify the oneline to note I'm modifying test-*.c.
