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
