* atomic_inc_return - atomically increment a counter and return previous.
50
* @v: handle to effective address of counter.
52
* Atomically increment a counter in system memory.
53
* The only restriction is that @v must be word aligned.
55
* This routine implements the "fetch and increment"
56
* primitive that is described in "Book I PowerPC User
57
* Instruction Set Architecture", but uses MFC lock line
58
* reservation operations instead of lwarx/stwcx.
60
* Returns the previous value from system memory.
