Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next
Pull sparc updates from David Miller:
"Largely this is simply adding support for the Niagara 4 cpu.
Major areas are perf events (chip now supports 4 counters and can
monitor any event on each counter), crypto (opcodes are availble for
sha1, sha256, sha512, md5, crc32c, AES, DES, CAMELLIA, and Kasumi
although the last is unsupported since we lack a generic crypto layer
Kasumi implementation), and an optimized memcpy.
Finally some cleanups by Peter Senna Tschudin."

*
- * The control register has two event fields, one for each of the two
- * counters. It's thus nearly impossible to have one counter going
- * while keeping the other one stopped. Therefore it is possible to
- * get overflow interrupts for counters not currently "in use" and

* unusual way to encode a NOP and therefore will not trigger in
* normal code.
+ *
+ * Starting with SPARC-T4 we have one control register per counter.
+ * And the counters are stored in individual registers. The registers
