Revert "prohibit rcutorture from being compiled into the kernel"
This reverts commit 9aaffc898ff4a3df18c5fc4b9e0fa47e779ad726. That commit was a very bad idea. RCU_TORTURE found many boot timing bugs and other sorts of bugs in the past, so excluding it from boot images is very silly. The option already depends on DEBUG_KERNEL and is disabled by default. Even when it runs, the test threads are reniced. If it annoys people we could add a runtime sysctl.

help
This option provides a kernel module that runs torture tests
on the RCU infrastructure. The kernel module may be built
after the fact on the running kernel to be tested, if desired.
+ Say Y here if you want RCU torture tests to start automatically
+ at boot time (you probably don't).
Say M if you want the RCU torture tests to build as a module.
Say N if you are unsure.
