git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull late ARM soc platform updates from Olof Johansson:
"This branch contains updates to OMAP and Marvell platforms (kirkwood,
dove, mvebu) that came in after we had done the big multiplatform
merges, so they were kept separate from the rest, and not separated
into the traditional topics of cleanup/driver/platform features.
For OMAP, the updates are:
- Runtime PM conversions for the GPMC and RNG IP blocks
- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and
non-4430 OMAP4
- OMAP hwmod code and data improvements
- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support
For Kirkwood/Dove/mvebu:
- New driver for "address decoder controller" for mvebu, which is a
piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP
since it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect
nand, mv_cesa and the above address decoder controller.
- Some defconfig updates, mostly to enable new DT boards and a few
drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and
mvebu
- New clean gpio driver for mvebu"

Pull powerpc updates from Benjamin Herrenschmidt:
"Some highlights in addition to the usual batch of fixes:
- 64TB address space support for 64-bit processes by Aneesh Kumar
- Gavin Shan did a major cleanup & re-organization of our EEH support
code (IBM fancy PCI error handling & recovery infrastructure) which
paves the way for supporting different platform backends, along
with some rework of the PCIe code for the PowerNV platform in order
to remove home made resource allocations and instead use the
generic code (which is possible after some small improvements to it
done by Gavin).
- Uprobes support by Ananth N Mavinakayanahalli
- A pile of embedded updates from Freescale folks, including new SoC
and board supports, more KVM stuff including preparing for 64-bit
BookE KVM support, ePAPR 1.1 updates, etc..."

Pull crypto update from Herbert Xu:
- Optimised AES/SHA1 for ARM.
- IPsec ESN support in talitos and caam.
- x86_64/avx implementation of cast5/cast6.
- Add/use multi-algorithm registration helpers where possible.
- Added IBM Power7+ in-Nest support.
- Misc fixes.
Fix up trivial conflicts in crypto/Kconfig due to the sparc64 crypto
config options being added next to the new ARM ones.
[ Side note: cut-and-paste duplicate help texts make those conflicts
harder to read than necessary, thanks to git being smart about
minimizing conflicts and maximizing the common parts... ]

For IPsec encryption, in the case when:
-the input buffer is fragmented (edesc->src_nents > 0)
-the output buffer is not fragmented (edesc->dst_nents = 0)
the ICV is not output in the link table, but after the encrypted payload.
Copying the ICV must be avoided in this case; consequently the condition
edesc->dma_len > 0 must be more specific, i.e. must depend on the type
of the output buffer - fragmented or not.
Testing was performed by modifying testmgr to support src != dst,
since currently native kernel IPsec does in-place encryption
(src == dst).

virt_to_abs() is just a wrapper around __pa(), use __pa() directly.
We should be including <asm/page.h> to get __pa(). abs_addr.h will be
removed shortly so drop that.
We were getting of.h via abs_addr.h so we need to include that directly.
Having done all that, clean up the ordering of the includes.

This patch adds the driver for interacting with the 842
compression accelerator on IBM Power7+ systems.
The device is a child of the Platform Facilities Option (PFO)
and shows up as a child of the IBM VIO bus.
The compression/decompression API takes the same arguments
as existing compression methods like lzo and deflate. The 842
hardware operates on 4K hardware pages and the driver breaks up
input on 4K boundaries to submit it to the hardware accelerator.

This patch creates a new submenu for the NX cryptographic
hardware accelerator and breaks the NX options into their own
Kconfig file under drivers/crypto/nx/Kconfig.
This will permit additional NX functionality to be easily
and more cleanly added in the future without touching
drivers/crypto/Makefile|Kconfig.

SHARE_WAIT, whilst more optimal for association-less crypto,
has the ability to start thrashing the CCB descriptor/key
caches, given high levels of traffic across multiple security
associations (and thus keys).
Switch to using the SERIAL sharing type, which prefers
the last used CCB for the SA. On a 2-DECO platform
such as the P3041, this can improve performance by
about 3.7%.

In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we first check "fsl,sec-v4.0",
if it fails, then check for "fsl,sec4.0".

commit "crypto: caam - use non-irq versions of spinlocks for job rings"
made two bad assumptions:
(a) The caam_jr_enqueue lock isn't used in softirq context.
Not true: jr_enqueue can be interrupted by an incoming net
interrupt and the received packet may be sent for encryption,
via caam_jr_enqueue in softirq context, thereby inducing a
deadlock.
This is evidenced when running netperf over an IPSec tunnel
between two P4080's, with spinlock debugging turned on:

(b) since the caam_jr_dequeue lock is only used in bh context,
then semantically it should use _bh spin_lock types. spin_lock_bh
semantics are to disable back-halves, and used when a lock is shared
between softirq (bh) context and process and/or h/w IRQ context.
Since the lock is only used within softirq context, and this tasklet
is atomic, there is no need to do the additional work to disable
back halves.
This patch adds back-half disabling protection to caam_jr_enqueue
spin_locks to fix (a), and drops it from caam_jr_dequeue to fix (b).

Initialization of cra_list is currently mixed, most ciphers initialize this
field and most shashes do not. Initialization however is not needed at all
since cra_list is initialized/overwritten in __crypto_register_alg() with
list_add(). Therefore perform cleanup to remove all unneeded initializations
of this field in 'crypto/drivers/'.

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."

commit "crypto: caam - use non-irq versions of spinlocks for job rings"
made two bad assumptions:
(a) The caam_jr_enqueue lock isn't used in softirq context.
Not true: jr_enqueue can be interrupted by an incoming net
interrupt and the received packet may be sent for encryption,
via caam_jr_enqueue in softirq context, thereby inducing a
deadlock.
This is evidenced when running netperf over an IPSec tunnel
between two P4080's, with spinlock debugging turned on:

(b) since the caam_jr_dequeue lock is only used in bh context,
then semantically it should use _bh spin_lock types. spin_lock_bh
semantics are to disable back-halves, and used when a lock is shared
between softirq (bh) context and process and/or h/w IRQ context.
Since the lock is only used within softirq context, and this tasklet
is atomic, there is no need to do the additional work to disable
back halves.
This patch adds back-half disabling protection to caam_jr_enqueue
spin_locks to fix (a), and drops it from caam_jr_dequeue to fix (b).

Commit feb7b7ab928afa97a79a9c424e4e0691f49d63be changed NSEC_PER_SEC to 64-bit
constant, which causes "DIV_ROUND_UP(NSEC_PER_SEC, dev->pk_clk_freq)" to
generate __divdi3 call on 32-bit archs. Fix this by changing DIV_ROUND_UP to
DIV_ROUND_UP_ULL.

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

The clk patches added code to get and enable clocks in the
respective driver probe functions. If the probe function failed
for some reason after enabling the clock, the clock was not
disabled again in many cases.
