- Update to 3.3-rc2. - Eliminated 5 patches. - Xen is disabled.
CONFIG_RCU_FAST_NO_HZ was finally an option for our desktop kernel flavors. You actually enabled it on x86_64 but not on i386, making i386/desktop our only x86 kernel flavor with CONFIG_RCU_FAST_NO_HZ disabled.
I can't really think of a good reason for that. Do I guess right that this was by mistake and i386/desktop should also have CONFIG_RCU_FAST_NO_HZ=y?
