Pull ARM SoC device tree conversions and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms. Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases."

2012-12-13ndisc: Fix padding error in link-layer address option.YOSHIFUJI Hideaki / 吉藤英明
If a natural number n exists where 2 + data_len <= 8n < 2 + data_len + pad, post padding is not initialized correctly. (Un)fortunately, the only type that requires pad is Infiniband, whose pad is 2 and data_len is 20, and this logical error has not become obvious, but it is better to fix. Note that ndisc_opt_addr_space() handles the situation described above correctly. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-12-13MIPS: Fix potencial corruptionRalf Baechle
Normally r4k_dma_cache_inv should only ever be called with cacheline aligned addresses. If however, it isn't there is the theoretical possibility of data corruption. There is no correct way of handling this and anyway, it should only happen if the DMA API is used incorrectly so drop There is a different corruption scenario with these CACHE instructions removed but again there is no way of handling this correctly and it can be triggered only through incorrect use of the DMA API.

2012-12-13MIPS: Handle COP3 Unusable exception as COP1X for FP emulationMaciej W. Rozycki
Our FP emulator is hardcoded for the MIPS IV FP instruction set and does not match the FP ISA with the general ISA. However for the few MIPS IV FP instructions that use the COP1X major opcode it relies on the Coprocessor Unusable exception to be delivered as a COP1 rather than COP3 exception. This includes indexed transfer (LDXC1, etc.) and FP multiply-accumulate (MADD.D, etc.) instructions. All the MIPS I, II, III and IV processors and some newer chips that do not implement the FPU use the COP3 exception however. Therefore I believe the kernel should follow and redirect any COP3 Unusable traps to the emulator unless an actual FPU part or core is present. This is a change that implements it. Any minor opcode encodings that are not recognised as valid FP instructions are rejected by the emulator and will result in a SIGILL signal being delivered as they currently do. We do not support vendor-specific coprocessor 3 implementations supported with MIPS I and MIPS II ISA processors; we never set CP0.Status.CU3. [Ralf: On MIPS IV processors the kernel always enables the XX bit which replaces the CU3 bit off earlier architecture revisions.] If matching between the CPU and the FPU ISA is considered required one day, this can still be done in the emulator itself. I think the CpU exception dispatcher is not the right place to do this anyway, as there are further differences between MIPS I, MIPS II, MIPS III, MIPS IV and MIPS32 FP ISAs. Corresponding explanation of this implementation is included within the change itself. Signed-off-by: Maciej W.

2012-12-13MIPS: Fix poweroff failure when HOTPLUG_CPU configured.Huacai Chen
When poweroff machine, kernel_power_off() call disable_nonboot_cpus(). And if we have HOTPLUG_CPU configured, disable_nonboot_cpus() is not an empty function but attempt to actually disable the nonboot cpus. Since system state is SYSTEM_POWER_OFF, play_dead() won't be called and thus disable_nonboot_cpus() hangs. Therefore, we make this patch to avoid poweroff failure.

2012-12-13MIPS: Remove usage of CEVT_R4K_LIB config option.Ralf Baechle
Manuel Lauss <manuel.lauss@gmail.com> writes: I introduced it as a fallback because early revisions of Alchemy hardware we shipped had a non-functional 32kHz timer and had to rely on the r4k timer instead. Previously the r4k timer was initialized regardless, but it's useless with the "wait" instruction. So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2012-12-13MIPS: Kconfig: Rename several firmware related config symbols.Ralf Baechle
With the upcoming merge of the ARC architecture there is a small likelyhood of conflicting use for the CONFIG_ARC config symbol. Rename it to CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64 to CONFIG_FW_ARC64. For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and CONFIG_CFE to CONFIG_FW_CFE.
