2013-11-13Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-09-13crypto: caam - split RNG4 instantiation functionAlex Porosanu

2013-09-13crypto: caam - fix RNG4 instantiationAlex Porosanu
The RNG4 block in CAAM needs to be 'seeded' first before being used for generating pseudo-random data. The 'seeding' is done by getting entropy from the TRNG ring oscillator. The RTFRQMAX register controls the maximum allowable number of samples that can be aquired during an entropy sample. Depending on the clock at which the RNG4 block (and for that matter the SEC block) runs, it's possible that a hard-coded value for the maximum frequency is inadequate, i.e. more samples than needed are taken. This is an error, and thus the RNG4 block doesn't get initialized. The patch attempts to alleviate this issue by trying with progressivly larger frequencies, until the number of samples is adequate. This patch also fixes how a descriptor is deemed as being finished: instead of checking the VALID field in the DECO debug register, it makes sure that the DECO is idle, by checking the DECO state field of the said register.

2013-09-13crypto: caam - fix RNG state handle instantiation descriptorAlex Porosanu
The way the DECO runs a descriptor through the direct (debug) interface is different from the JRI interface: the DECO will continue to try and execute the next commands, after the descriptor buffer has ended. This leads to unpredictable results and possibly to locking up of the DECO. This patch adds a halt command at the end of the descriptor to ensure the DECO halts when it reaches the end of the descriptor buffer.

2013-09-13crypto: tegra - use kernel entropy instead of ad-hocLinus Walleij
The way I read the Tegra AES RNG is that it has a homebrew algorithm for initializing the 128bit RNG using timespec and the unique chip ID. This looks like reinventing the (square) wheel, instead just grab 128bits from the kernel entropy pool where the time and (after another patch) chip unique ID is already mixed in. Incidentally this also gets rid of a rather ugly cross-dependence on the machine using an extern declaration.

2013-09-02crypto: nx - fix GCM for zero length messagesMarcelo Cerri
The NX CGM implementation doesn't support zero length messages and the current implementation has two flaws: - When the input data length is zero, it ignores the associated data. - Even when both lengths are zero, it uses the Crypto API to encrypt a zeroed block using ctr(aes) and because of this it allocates a new transformation and sets the key for this new tfm. Both operations are intended to be used only in user context, while the cryptographic operations can be called in both user and softirq contexts. This patch replaces the nested Crypto API use and adds two special cases: - When input data and associated data lengths are zero: it uses NX ECB mode to emulate the encryption of a zeroed block using ctr(aes). - When input data is zero and associated data is available: it uses NX GMAC mode to calculate the associated data MAC.
