[PATCH 0/2] Fix objtool warnings if LTO is enabled for LoongArch

[Tiezhu Yang]

The patch #1 should be a preparation for patch #2, that is to say,
the patch #2 is dependent on the patch #1, otherwise there is build
error if LTO is enabled after only applying patch #2.

With this series, most of warnings have been silenced, only remains
the following warning by now, it needs more analysis:

  vmlinux.o: warning: objtool: __efistub_efi_boot_kernel() falls through
  to next function __efistub_exit_boot_func()

How to reproduce:

  $ make ARCH=loongarch LLVM=1 clean defconfig
  $ scripts/config -d LTO_NONE -e LTO_CLANG_THIN
  $ make ARCH=loongarch LLVM=1 olddefconfig all

Tiezhu Yang (2):
  objtool/LoongArch: Get table size correctly if LTO is enabled
  LoongArch: Pass annotate-tablejump option if LTO is enabled
