This adds support for the A31 Hummingbird: http://www.merrii.com/en/pla_d.asp?id=172 The Merrii A31 Hummingbird is a development board based on the Allwinner A31 SoC with multiple USB ports through a USB hub chip, a uSD slot, a 10/100/1000M ethernet port, an AP6210 WiFi/BT chip, TV-in, HDMI, VGA, audio in/out ports, and LCD/CSI headers.

The A23 has the same MMIO reset controllers matching the clocks gates, just like in the A31. This patch adds the reset controller nodes and the reset control phandles for the peripherals needing them to the DTSI. Unlike the sun6i DTSI, this patch uses sun6i-a31-clock-reset for ahb1_rst. sun6i-a31-ahb-reset is for early init, and requires some additions to the machine code. It is used to support the hstimer. However the hstimer on sun8i only has 1 timer, which is somewhat useless. Support for it will probably not be added. Hence the decision to use sun6i-a31-clock-reset here to avoid the changes to sun8i machine code.

Patch to prevent warning of a buggy compiler when using clang and the ARM_UNWIND option. Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and GNUC_PATCHLEVEL to 4, 2, and 1 respectively. This version of GCC gets flagged as buggy, but it isn't actually an issue with clang so the patch will do what it did before unless clang is defined and then it will not report the GCC version as an issue.

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x. MPU DPLL has a limitation on the maximum frequency it can be locked at. Duty Cycle Correction circuit is used to recover a correct duty cycle for achieving higher frequencies (hardware internally switches output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)). For further information, See the note on OMAP5432 Technical Reference Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters", and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5" chapter 2.1 "Micro Processor Unit (MPU)".

It is better not to think about compute capacity as being equivalent to "CPU power". The upcoming "power aware" scheduler work may create confusion with the notion of energy consumption if "power" is used too liberally. This contains the architecture visible changes. Incidentally, only ARM takes advantage of the available pow^H^H^Hcapacity scaling hooks and therefore those changes outside kernel/sched/ are confined to one ARM specific file. The default arch_scale_smt_power() hook is not overridden by anyone. Replacements are as follows: arch_scale_freq_power --> arch_scale_freq_capacity arch_scale_smt_power --> arch_scale_smt_capacity SCHED_POWER_SCALE --> SCHED_CAPACITY_SCALE SCHED_POWER_SHIFT --> SCHED_CAPACITY_SHIFT The local usage of "power" in arch/arm/kernel/topology.c is also changed to "capacity" as appropriate.

Currently hugepage migration is available for all archs which support pmd-level hugepage, but testing is done only for x86_64 and there're bugs for other archs. So to avoid breaking such archs, this patch limits the availability strictly to x86_64 until developers of other archs get interested in enabling this feature. Simply disabling hugepage migration on non-x86_64 archs is not enough to fix the reported problem where sys_move_pages() hits the BUG_ON() in follow_page(FOLL_GET), so let's fix this by checking if hugepage migration is supported in vma_migratable().
