* Most instructions on the Ubicom32 processor are atomic in that they
* execute in one clock cycle. However, Linux has several operations
* (e.g. compare and swap) which will require more than a single instruction
* to perform. To achieve this, the Ubicom32 processor uses a single
* global bit in a scratchpad register as a critical section lock. All
* atomic operations acquire this lock.
*
* NOTE: To AVOID DEADLOCK(s), the atomic lock must only be used for atomic
* operations or by the ldsr to avoid disabling a thread performing an atomic
* operation.
*
* Do not attempt to disable interrupts while holding the atomic operations
* lock or you will DEADLOCK the system.
