tristate "Generic Hardware Spinlock framework"
help
Say y here to support the generic hardware spinlock framework.
You only need to enable this if you have hardware spinlock module
on your system (usually only relevant if your system has remote slave
coprocessors).
If unsure, say N.

Add a platform-independent hwspinlock framework. Hardware spinlock devices are needed, e.g., in order to access data that is shared between remote processors, that otherwise have no alternative mechanism to accomplish synchronization and mutual exclusion operations.
