 +config HAVE_MOD_ARCH_SPECIFIC
 +      bool
 +      help
 +        The arch uses struct mod_arch_specific to store data.  Many arches
 +        just need a simple module loader without arch specific data - those
 +        should not enable this.
 +
 +config MODULES_USE_ELF_RELA
 +      bool
 +      help
 +        Modules only use ELF RELA relocations.  Modules with ELF REL
 +        relocations will give an error.
 +
 +config MODULES_USE_ELF_REL
 +      bool
 +      help
 +        Modules only use ELF REL relocations.  Modules with ELF RELA
 +        relocations will give an error.
 +
+ config HAVE_RCU_USER_QS
+       bool
+       help
+         Provide kernel entry/exit hooks necessary for userspace
+         RCU extended quiescent state. Syscalls need to be wrapped inside
+         rcu_user_exit()-rcu_user_enter() through the slow path using
+         TIF_NOHZ flag. Exceptions handlers must be wrapped as well. Irqs
+         are already protected inside rcu_irq_enter/rcu_irq_exit() but
+         preemption or signal handling on irq exit still need to be protected.
+ 
+ config HAVE_VIRT_CPU_ACCOUNTING
+       bool
+ 
+ config HAVE_IRQ_TIME_ACCOUNTING
+       bool
+       help
+         Archs need to ensure they use a high enough resolution clock to
+         support irq time accounting and then call enable_sched_clock_irqtime().
