The caam job rings (input/output job ring) are allocated using
dma_map_single(). These job rings can be visualized as the ring
buffers in which the jobs are en-queued/de-queued. The s/w enqueues
the jobs in input job ring which h/w dequeues and after processing
it copies the jobs in output job ring. Software then de-queues the
job from output ring. Using dma_map/unmap_single() is not preferred
way to allocate memory for this type of requirements because this
adds un-necessary complexity.
Example, if bounce buffer (SWIOTLB) will get used then to make any
change visible in this memory to other processing unit requires
dmap_unmap_single() or dma_sync_single_for_cpu/device(). The
dma_unmap_single() can not be used as this will free the bounce
buffer, this will require changing the job rings on running system
and I seriously doubt that it will be not possible or very complex
to implement. Also using dma_sync_single_for_cpu/device() will also
add unnecessary complexity.
The simple and preferred way is using dma_alloc_coherent() for these
type of memory requirements.
This resolves the Linux boot crash issue when "swiotlb=force" is set
in bootargs on systems which have memory more than 4G.

there is no noticeable benefit for multiple cores to process one
job ring's output ring: in fact, we can benefit from cache effects
of having the back-half stay on the core that receives a particular
ring's interrupts, and further relax general contention and the
locking involved with reading outring_used, since tasklets run
atomically.

Memory barriers are implied by the i/o register write implementation
(at least on Power). So we can remove the redundant wmb() in

It has been observed that in zero-loss benchmarks, when a
slow traffic rate is being tested, the IRQ timer coalescing
parameter was set too high, and the ethernet controller
would start dropping packets because the job ring back half
wouldn't be executed in time before the ethernet controller
would fill its buffers, thereby significantly reducing the
zero-loss performance figures.
Empirical testing has shown that the best zero-loss performance
is achieved when IRQ coalescing is set to minimum values and/or
turned off, since apparently the job ring driver already implements
an adequately-performing general-purpose IRQ mitigation strategy
in software.
Whilst we could go with minimal count (2-8) and timing settings
(192-256), we prefer just turning h/w coalescing altogether off
to minimize setkey latency (due to split key generation), and
for consistent cross-SoC performance (the SEC vs. core clock
ratio changes).

crypto: ux500 - Add driver for CRYP hardware
hwrng: Kconfig - modify default state for atmel-rng driver
hwrng: omap - use devm_request_and_ioremap
crypto: crypto4xx - move up err_request_irq label
crypto, xor: Sanitize checksumming function selection output
crypto: caam - add backward compatible string sec4.0
Pull powerpc updates from Benjamin Herrenschmidt:
"Here are the powerpc goodies for 3.5. Main highlights are:
- Support for the NX crypto engine in Power7+
- A bunch of Anton goodness, including some micro optimization of our
syscall entry on Power7
- I converted a pile of our thermal control drivers to the new i2c
APIs (essentially turning the old therm_pm72 into a proper set of
windfarm drivers). That's one more step toward removing the
deprecated i2c APIs, there's still a few drivers to fix, but we are
getting close
- kexec/kdump support for 47x embedded cores
The big missing thing here is no updates from Freescale. Not sure
what's up here, but with Kumar not working for them anymore things are
a bit in a state of flux in that area."
