Merge tag 'kbuild-thinar-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild thin archives updates from Masahiro Yamada: "Thin archives migration by Nicholas Piggin. THIN_ARCHIVES has been available for a while as an optional feature only for PowerPC architecture, but we do not need two different intermediate-artifact schemes. Using thin archives instead of conventional incremental linking has various advantages: - save disk space for builds - speed-up building a little - fix some link issues (for example, allyesconfig on ARM) due to more flexibility for the final linking - work better with dead code elimination we are planning As discussed before, this migration has been done unconditionally so that any problems caused by this will show up with "git bisect". With testing with 0-day and linux-next, some architectures actually showed up problems, but they were trivial and all fixed now" * tag 'kbuild-thinar-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: tile: remove unneeded extra-y in Makefile kbuild: thin archives make default for all archs x86/um: thin archives build fix tile: thin archives fix linking ia64: thin archives fix linking sh: thin archives fix linking kbuild: handle libs-y archives separately from built-in.o archives kbuild: thin archives use P option to ar kbuild: thin archives final link close --whole-archives option ia64: remove unneeded extra-y in Makefile.gate tile: fix dependency and .*.cmd inclusion for incremental build sparc64: Use indirect calls in hamming weight stubs
