[PATCH 0/6] kbuild: strive to avoid $(shell ...) invocations

[Masahiro Yamada]

$(shell ...) forks process(es).
Built-in functions are more efficient.



Masahiro Yamada (6):
  kbuild: add test-{le,ge,lt,gt} macros
  kbuild: make CONFIG_*_VERSION always 6-digit
  kbuild: implement {gcc,clang}-min-version only with built-in functions
  kbuild: add read-file macro
  kconfig: refactor Makefile to reduce process forks
  kbuild: check Make version
