Thank you! I have reverted the earlier version to queue this one. Please check below to make sure that my usual wordsmithing did not mess things up.
Mark, any suggestions for any needed ARM CFcommon.arch files? Or does moving out the x86/PowerPC-specific Kconfig options take care of things for you guys? (Hey, I can dream, can't I?)
I'm not aware of anything that we specifically need enabled, so pulling out those bits should be everything -- I've given my Ack below.
Sometimes dreams come true? ;-)
And thank you -- I will apply your ack on my next rebase.
Thanx, Paul

rcutorture: Add CFcommon.arch for arch-specific Kconfig optionsAdd CFcommon.arch for arch-specific Kconfig options. In accordance with [1], [2] and [3], move the x86-specific kernel option CONFIG_HYPERVISOR_GUEST to CFcommon.i686 and CFcommon.x86_64, and also move the x86/PowerPC CONFIG_KVM_GUEST Kconfig option to CFcommon.i686, CFcommon.x86_64, and CFcommon.ppc64le. The "arch" in CFcommon.arch is taken from the "uname -m" command.
