Linux Kernels 4.11.3, 4.9.30 LTS, 4.4.70 LTS and 3.18.55 Bring PPC and ARM Fixes

These new kernel patches are here only five days after the release of their previous versions, and it looks like most of the changes are improvements for ARM, ARM64 (AArch64), and PowerPC (PPC) hardware architectures, though the s390, x86, MetaG, UM, MIPS and Alpha arches also received a bit of attention. Numerous drivers have been updated as well, including those for USB, Watchdog, PCI, UWB, SCSI, NVDIMM, wireless (ath9k, rtlwifi, mwifiex), IrDA, InfiniBand, IOMMU, MD, iiO, GPU (AMDGPU, Intel i915, Nouveau), GPIO, ACPI, EDAC, CPUIdle, and MTD devices.
