Waiting for a solution to this issue, this patch disables the CPU Idle support for this SoC. As CPU Hot plug support also uses some of the CPU Idle functions it is also affected by the same issue. This patch disables it also for the Armada 38x SoCs.

This allows us to create a new thermal zone (called, un-imaginatively "board"), and allows us to use some active cooling as temperatures start edge upward in the system by creating a new alert temperature (emperically 50C) for cpu. NOTE: Fan is NOT mounted by default on the platform, in such a case, all we end up doing is switch on a regulator and leak very minimal current.

The patch adds 5 thermal sensors. Only one cooling device for mpu as of now. The sensors are the exact same on both dra72 and dra7. Introduce CPU, GPU, core nodes for the moment as they are direct reuse of OMAP5 entities. NOTE: OMAP4 has a finer counter granularity, which allows for a delay of 1000ms in the thermal zone polling intervals. DRA7 have different counter mechanism, which allows at maximum a 500ms timer. Adjust the cpu thermal zone accordingly for DRA7.

The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be enabled. These options inherit a dependency from an enclosing menu, that requires ARCH_MULTIPLATFORM to be 'enabled'. This is a contradiction and made this option also unavailable for non-multiplatform configurations. Since there are no selects on OMAP4_ERRATA_I688, which would ignore dependencies, the code related to that option is dead and can be removed. This (logical) defect has been found with the undertaker tool.

So, use arch/arm/plat-omap/Kconfig and the existing pm.c source as a guide, and posit that deep power saving states are only supported on OMAP16xx chips with kernels built with both CONFIG_OMAP_DM_TIMER=y and CONFIG_OMAP_32K_TIMER=y. While here, clean up a few printk()s and unnecessary #ifdefs. This second version of the patch incorporates several suggestions from Jon Hunter <jgchunter@gmail.com>.

Also from Sowmini Varadhan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc: Use GFP_ATOMIC in ldc_alloc_exp_dring() as it can be called in softirq context sparc64: Use M7 PMC write on all chips T4 and onward. iommu-common: rename iommu_pool_hash to iommu_hash_common iommu-common: fix x86_64 compiler warnings
