  kernel hacking: support building kernel with -Og optimization level
(2018-11-19 23:32:54 +0900)

----------------------------------------------------------------
Kbuild updates for v4.21 (part 2)

Debugging experience improvement by Changbin Du.

Support -Og optimization level, which offers a reasonable level of
optimization while maintaining a good debugging experience.

Introduce a new option CONFIG_NO_AUTO_INLINE as well. With this option,
only functions explicitly marked with "inline" will be inlined. This
will allow the function tracer to trace more functions.

----------------------------------------------------------------
Changbin Du (5):
      x86/mm: declare check_la57_support() as inline
      openrisc: make function cache_loop() inline
      kernel hacking: add a config option to disable compiler auto-inlining
      ARM: mm: fix build error in fix_to_virt with -Og optimization level
      kernel hacking: support building kernel with -Og optimization level
