I compile tested it. Then I got bored trying to hunt down all the
Kconfig things I needed to turn on to runtime test it ;)
btw, I suggest using HAVE_LIVE_PATCHING instead of
ARCH_HAVE_LIVE_PATCHING. because this:
akpm3:/usr/src/25> grep " HAVE_" arch/x86/Kconfig | wc -l
67
akpm3:/usr/src/25> grep " ARCH_HAVE_" arch/x86/Kconfig | wc -l
3
akpm3:/usr/src/25> grep " ARCH_HAS_" arch/x86/Kconfig | wc -l
7
akpm3:/usr/src/25> grep " HAVE_ARCH" arch/x86/Kconfig | wc -l
8
akpm3:/usr/src/25> grep " ARCH_USE" arch/x86/Kconfig | wc -l
4
akpm3:/usr/src/25> grep " ARCH_WANT" arch/x86/Kconfig | wc -l
6
makes me cry.
