+Subject: [PATCH 103/191] locking: don't check for __LINUX_SPINLOCK_TYPES_H on
+ -RT archs
+
+Upstream uses arch_spinlock_t within spinlock_t and requests that
+spinlock_types.h header file is included first.
+On -RT we have the rt_mutex with its raw_lock wait_lock which needs
+architectures' spinlock_types.h header file for its definition. However
+we need rt_mutex first because it is used to build the spinlock_t so
+that check does not work for us.
+Therefore I am dropping that check.
+
