Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux

Pull ARM updates from Russell King:

 - clean up TTBCR magic numbers and use u32 for this register

 - fix clang issue in VFP code leading to kernel oops, caused by
   compiler instruction scheduling.

 - switch 32-bit Arm to use GENERIC_CPU_DEVICES and use the
   arch_cpu_is_hotpluggable() hook.

 - pass struct device to arm_iommu_create_mapping() and move over to use
   iommu_paging_domain_alloc() rather than iommu_domain_alloc()

 - make amba_bustype constant
