Subject: linux-next: build warnings after merge of the kbuild tree

Hi Michal,

After merging the kbuild tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

Cyclomatic Complexity 1 scripts/mod/devicetable-offsets.c:main
Cyclomatic Complexity 1 kernel/bounds.c:foo
Cyclomatic Complexity 1 arch/x86/kernel/asm-offsets_64.c:main
Cyclomatic Complexity 1 arch/x86/kernel/asm-offsets.c:common
Cyclomatic Complexity 5 arch/x86/ia32/audit.c:ia32_classify_syscall

and so on (many, many of these - about 635,000 :-()

Introduced (presumably) by commits

  6b90bd4ba40b ("GCC plugin infrastructure")
  0dae776c6bf3 ("Add Cyclomatic complexity GCC plugin")

I have disabled CONFIG_GCC_PLUGIN_CYC_COMPLEXITY (by making it depend
on CONFIG_BROKEN) until it is not enabled by default.
