Merge branch 'kbuild-next-speedups' into kbuild-for-next

* kbuild-next-speedups:
  kbuild: Mark the initcall ordering recipe as recursive
  kbuild: Mark the gzip recipes as recursive
  kconfig: Improve ergonomics around disabling warnings with cc-option
  scripts/Kconfig.toolchain: Drop compiler symbols from dependencies
  kbuild: keep .modinfo when vmlinux is linked with --gc-sections
  kbuild: compress the kernel with pigz if available
  kbuild: avoid re-running compiler and linker probes
  kbuild: move the toolchain checks into scripts/Kconfig.toolchain
  kallsyms: reimplement mksysmap in C
  elf-parse: add section flags, symbol binding and mapping helpers
  kbuild: only emit vmlinux relocations when required
  kbuild: do not sort nm output where the order is irrelevant
  sorttable: parse nm output correctly
  kallsyms: output binary data to speed output and kallsyms assembly
  kallsyms: index symbols by token to speed up table compression
  kbuild: do not allocate .modinfo in vmlinux
