2012-10-07Merge tag 'soc-late' of ↵Linus Torvalds1-2/+15
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" * tag 'soc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (98 commits) ARM: mvebu: fix build breaks from multi-platform conversion ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70 ARM: OMAP2+: PMU: Add runtime PM support ARM: OMAP4430: PMU: prepare to create PMU device via HWMOD ARM: OMAP2+: PMU: Convert OMAP2/3 devices to use HWMOD ARM: OMAP3: hwmod data: Add debugss HWMOD data ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU clockdomain idle problems ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP hwrng: OMAP: remove SoC restrictions from driver registration ARM: OMAP: split OMAP1, OMAP2+ RNG device registration hwrng: OMAP: convert to use runtime PM hwrng: OMAP: store per-device data in per-device variables, not file statics ARM: OMAP2xxx: hwmod/CM: add RNG integration data ARM: OMAP2+: gpmc: minimal driver support ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2/3: hwmod data: add gpmc ARM: OMAP4: hwmod data: add mmu hwmod for ipu and dsp ARM: OMAP3: hwmod data: add mmu data for iva and isp ARM: OMAP: iommu: fix including iommu.h without IOMMU_API selected ARM: OMAP4: hwmod data: add missing HWMOD_NO_IDLEST flags to some PRCM IP blocks ...

2012-08-28crypto: talitos - fix icv management on outbound directionHoria Geanta1-1/+1
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).

2012-08-20crypto: caam - fix possible deadlock conditionKim Phillips1-5/+5
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: [ 892.092569] BUG: spinlock lockup on CPU#7, netperf/10634, e8bf5f70 [ 892.098747] Call Trace: [ 892.101197] [eff9fc10] [c00084c0] show_stack+0x48/0x15c (unreliable) [ 892.107563] [eff9fc50] [c0239c2c] do_raw_spin_lock+0x16c/0x174 [ 892.113399] [eff9fc80] [c0596494] _raw_spin_lock+0x3c/0x50 [ 892.118889] [eff9fc90] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.124550] [eff9fcd0] [c044a644] aead_decrypt+0x6c/0xc8 [ 892.129625] BUG: spinlock lockup on CPU#5, swapper/5/0, e8bf5f70 [ 892.129629] Call Trace: [ 892.129637] [effa7c10] [c00084c0] show_stack+0x48/0x15c (unreliable) [ 892.129645] [effa7c50] [c0239c2c] do_raw_spin_lock+0x16c/0x174 [ 892.129652] [effa7c80] [c0596494] _raw_spin_lock+0x3c/0x50 [ 892.129660] [effa7c90] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.129666] [effa7cd0] [c044a644] aead_decrypt+0x6c/0xc8 [ 892.129674] [effa7d00] [c0509724] esp_input+0x178/0x334 [ 892.129681] [effa7d50] [c0519778] xfrm_input+0x77c/0x818 [ 892.129688] [effa7da0] [c050e344] xfrm4_rcv_encap+0x20/0x30 [ 892.129697] [effa7db0] [c04b90c8] ip_local_deliver+0x190/0x408 [ 892.129703] [effa7de0] [c04b966c] ip_rcv+0x32c/0x898 [ 892.129709] [effa7e10] [c048b998] __netif_receive_skb+0x27c/0x4e8 [ 892.129715] [effa7e80] [c048d744] netif_receive_skb+0x4c/0x13c [ 892.129726] [effa7eb0] [c03c28ac] _dpa_rx+0x1a8/0x354 [ 892.129732] [effa7ef0] [c03c2ac4] ingress_rx_default_dqrr+0x6c/0x108 [ 892.129742] [effa7f10] [c0467ae0] qman_poll_dqrr+0x170/0x1d4 [ 892.129748] [effa7f40] [c03c153c] dpaa_eth_poll+0x20/0x94 [ 892.129754] [effa7f60] [c048dbd0] net_rx_action+0x13c/0x1f4 [ 892.129763] [effa7fa0] [c003d1b8] __do_softirq+0x108/0x1b0 [ 892.129769] [effa7ff0] [c000df58] call_do_softirq+0x14/0x24 [ 892.129775] [ebacfe70] [c0004868] do_softirq+0xd8/0x104 [ 892.129780] [ebacfe90] [c003d5a4] irq_exit+0xb8/0xd8 [ 892.129786] [ebacfea0] [c0004498] do_IRQ+0xa4/0x1b0 [ 892.129792] [ebacfed0] [c000fad8] ret_from_except+0x0/0x18 [ 892.129798] [ebacff90] [c0009010] cpu_idle+0x94/0xf0 [ 892.129804] [ebacffb0] [c059ff88] start_secondary+0x42c/0x430 [ 892.129809] [ebacfff0] [c0001e28] __secondary_start+0x30/0x84 [ 892.281474] [ 892.282959] [eff9fd00] [c0509724] esp_input+0x178/0x334 [ 892.288186] [eff9fd50] [c0519778] xfrm_input+0x77c/0x818 [ 892.293499] [eff9fda0] [c050e344] xfrm4_rcv_encap+0x20/0x30 [ 892.299074] [eff9fdb0] [c04b90c8] ip_local_deliver+0x190/0x408 [ 892.304907] [eff9fde0] [c04b966c] ip_rcv+0x32c/0x898 [ 892.309872] [eff9fe10] [c048b998] __netif_receive_skb+0x27c/0x4e8 [ 892.315966] [eff9fe80] [c048d744] netif_receive_skb+0x4c/0x13c [ 892.321803] [eff9feb0] [c03c28ac] _dpa_rx+0x1a8/0x354 [ 892.326855] [eff9fef0] [c03c2ac4] ingress_rx_default_dqrr+0x6c/0x108 [ 892.333212] [eff9ff10] [c0467ae0] qman_poll_dqrr+0x170/0x1d4 [ 892.338872] [eff9ff40] [c03c153c] dpaa_eth_poll+0x20/0x94 [ 892.344271] [eff9ff60] [c048dbd0] net_rx_action+0x13c/0x1f4 [ 892.349846] [eff9ffa0] [c003d1b8] __do_softirq+0x108/0x1b0 [ 892.355338] [eff9fff0] [c000df58] call_do_softirq+0x14/0x24 [ 892.360910] [e7169950] [c0004868] do_softirq+0xd8/0x104 [ 892.366135] [e7169970] [c003d5a4] irq_exit+0xb8/0xd8 [ 892.371101] [e7169980] [c0004498] do_IRQ+0xa4/0x1b0 [ 892.375979] [e71699b0] [c000fad8] ret_from_except+0x0/0x18 [ 892.381466] [e7169a70] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.387127] [e7169ab0] [c044ad4c] aead_givencrypt+0x6ac/0xa70 [ 892.392873] [e7169b20] [c050a0b8] esp_output+0x2b4/0x570 [ 892.398186] [e7169b80] [c0519b9c] xfrm_output_resume+0x248/0x7c0 [ 892.404194] [e7169bb0] [c050e89c] xfrm4_output_finish+0x18/0x28 [ 892.410113] [e7169bc0] [c050e8f4] xfrm4_output+0x48/0x98 [ 892.415427] [e7169bd0] [c04beac0] ip_local_out+0x48/0x98 [ 892.420740] [e7169be0] [c04bec7c] ip_queue_xmit+0x16c/0x490 [ 892.426314] [e7169c10] [c04d6128] tcp_transmit_skb+0x35c/0x9a4 [ 892.432147] [e7169c70] [c04d6f98] tcp_write_xmit+0x200/0xa04 [ 892.437808] [e7169cc0] [c04c8ccc] tcp_sendmsg+0x994/0xcec [ 892.443213] [e7169d40] [c04eebfc] inet_sendmsg+0xd0/0x164 [ 892.448617] [e7169d70] [c04792f8] sock_sendmsg+0x8c/0xbc [ 892.453931] [e7169e40] [c047aecc] sys_sendto+0xc0/0xfc [ 892.459069] [e7169f10] [c047b934] sys_socketcall+0x110/0x25c [ 892.464729] [e7169f40] [c000f480] ret_from_syscall+0x0/0x3c (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.

2012-08-01powerpc/crypto: add 842 hardware compression driverSeth Jennings3-0/+1627
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.

2012-08-01crypto: caam - set descriptor sharing type to SERIALKim Phillips3-7/+7
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%.

2012-08-01crypto: drivers - remove cra_list initializationJussi Kivilinna12-21/+0
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/'.

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.

2012-07-19n2_crypto: remove IRQF_SAMPLE_RANDOM which is now a no-opTheodore Ts'o1-2/+1
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.
