2013-04-25[media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_capMauro Carvalho Chehab
After cx25821-video cleanup, this var is not used anymore: drivers/media/pci/cx25821/cx25821-video.c: In function 'cx25821_vidioc_try_fmt_vid_cap': drivers/media/pci/cx25821/cx25821-video.c:591:15: warning: variable 'maxw' set but not used [-Wunused-but-set-variable] as the code now checks the max width as the default case for the range check.

2013-04-25[media] r820t: Remove a warning for an unused valueMauro Carvalho Chehab
Currently, the driver complains about the pre_detect var: drivers/media/tuners/r820t.c: In function 'r820t_sysfreq_sel': drivers/media/tuners/r820t.c:722:31: warning: variable 'pre_dect' set but not used [-Wunused-but-set-variable] While rtl8232 code comments it, perhaps some other driver may use.

2013-04-25[media] dib0090: Fix a warning at dib0090_set_EFUSEMauro Carvalho Chehab
The check if the values for c, h and n are within the range is always true, as, if one of this values is out of range, the previous "if" clauses will default to a value within the range. That fixes the following warning: drivers/media/dvb-frontends/dib0090.c: In function 'dib0090_set_EFUSE': drivers/media/dvb-frontends/dib0090.c:1545:5: warning: comparison is always true due to limited range of data type [-Wtype-limits] and makes the code easier to read.

2013-04-25[media] dib8000: Fix sub-channel rangeMauro Carvalho Chehab
isdbt_sb_subchannel is unsigned with 8 bits. So, it will never be -1. Instead, any value bigger than 13 is invalid. As is, the current code generates the following warnings: drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_set_isdbt_common_channel': drivers/media/dvb-frontends/dib8000.c:2358:3: warning: comparison is always true due to limited range of data type [-Wtype-limits] drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_tune': drivers/media/dvb-frontends/dib8000.c:3107:8: warning: comparison is always false due to limited range of data type [-Wtype-limits] drivers/media/dvb-frontends/dib8000.c:3153:9: warning: comparison is always false due to limited range of data type [-Wtype-limits] drivers/media/dvb-frontends/dib8000.c:3160:5: warning: comparison is always false It should also be noticed that ARIB STD-B31, item "3.15.6.8 Number of segments" at TMCC table defines the value 15 for unused segment, and 14 as reserved. So, better to change the check to consider any value bigger than 13 to mean that sub-channels should be disabled, fixing the warning and doing the right thing even if an invalid value is filled by userspace.

2013-04-25USB: OHCI: avoid conflicting platform driversArnd Bergmann
Like the EHCI driver, OHCI supports a large number of different platform glue drivers by directly including them, which causes problems with conflicting macro definitions in some cases. As more ARM architecture specific back-ends are required to coexist in a single build, we should split those out into separate drivers. Unfortunately, the infrastructure for that is still under development, so to give us more time, this uses a separate *_PLATFORM_DRIVER macro for each ARM specific OHCI backend, just like we already do on PowerPC and some of the other ARM platforms. In linux-3.10, only the SPEAr and CNS3xxx back-ends would actually conflict without this patch, but over time we would get more of them, so this is a way to avoid having to patch the driver every time it breaks. We should still split out all back-ends into separate loadable modules, but that work is only needed to improve code size and cleanliness after this patch, not for correctness. While we're here, this fixes the incorrectly sorted error path for the OMAP1 and OMAP3 backends to ensure we always unregister the exact set of drivers that were registered before erroring out.

2013-04-25arm64: Survive invalid cpu enable-methodsMark Rutland
Currently, if you pass the kernel a dtb where a cpu node has an unsupported enable-method property (e.g. "not-psci"), it'll explode horribly, as it iterates over the enable_ops array incorrectly. It increments the pointer *at* the current element, rather than incrementing the pointer *to* the current element. As the first two elements pointed to structures that were contiguous in memory, this happened to be equivalent. However the third element is NULL, so when the list is exhausted, smp_get_enable_ops generates the wrong pointer, and dereferences an arbitrary portion of memory, which currently happens to contain zero. This patch fixes this by indirecting the pointer one level, so we iterate over the array elements correctly, avoiding the below panic: Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-04-25arm64: mm: Correct show_pte behaviourSteve Capper
show_pte makes use of the *_none_or_clear_bad style functions. If a pgd, pud or pmd is identified as being bad, it will then be cleared. As show_pte appears to be called from either the user or kernel fault handlers this side effect can lead to unpredictable behaviour; especially as TLB entries are not invalidated. This patch removes the page table sanitisation from show_pte. If a bad pgd, pud or pmd is encountered it is left unmodified.

2013-04-25[media] dib8000: store dtv_property_cache in a temp varMauro Carvalho Chehab
dtv_property_cache is used on several places on very long lines. On all places it is used, a long list of struct reference is done. Instead of doing it, at the routines where it is used more than once, replace it by one temporary var. That may help the compiler to use a better code. It also makes easier to review the code, as the lines becomes closer to 80 columns, making them a way clearer to read. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

camellia cipher Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring 32 parallel blocks for input (512 bytes). Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards.

2013-04-25crypto: x86 - add more optimized XTS-mode for serpent-avxJussi Kivilinna
This patch adds AVX optimized XTS-mode helper functions/macros and converts serpent-avx to use the new facilities.
