[PATCH V2] rcutorture: Add CFcommon.arch for the various arch's need

by Zhouyi Zhou

Add CFcommon.arch for the various arch's need for rcutorture. According to [1] and [2], this patch Fixes: a6fda6dab93c ("rcutorture: Tweak kvm options") by moving x86 specific kernel option CONFIG_HYPERVISOR_GUEST to CFcommon.x86 [1] https://lore.kernel.org/all/20240427005626.1365935-1-zhouzhouyi@gmail.com/ [2] https://lore.kernel.org/all/059d36ce-6453-42be-a31e-895abd35d590@paulmck-la… Tested in x86_64 and PPC VM of Open Source Lab of Oregon State University. Signed-off-by: Zhouyi Zhou <zhouzhouyi(a)gmail.com> --- Hi Paul, I tried very hard to find in Linux kernel on how to dig out the x86 specific kernel option CONFIG_HYPERVISOR_GUEST before configcheck.sh generates ConfigFragment.diags. I can only find this functionality in scripts/kconfig/conf which travels the Kconfig hierarchy. But the output of scripts/kconfig/conf, which is .config is also one of the input of configcheck.sh: ``` kvm-recheck.sh: configcheck.sh $i/.config $i/ConfigFragment > $i/ConfigFragment.diags 2>&1 ``` I feel some logic paradox in it ;-) So, I pick the simplest way. One more thing, recent change in include/linux/bitmap.h cause the make of allmodconfig fail because of warning on both x86 platforms, I am going to do research on it.
