Linux kernels 4.4.74 LTS and 3.18.58 are small patches, and among the things that received attention, we can mention the x86, MIPS, s390, PA-RISC, Xtensa, ARM, ARC, F-RV, SPARC, SH, PowerPC (PPC), and TILE hardware architectures, as well as the USB (dwc3-exynos, net2280, r8a66597-hcd, xhci-pci), CPUFreq, iiO (as3935), MFD (omap-usb-tll), media (pvrusb2 and videobuf2), networking, staging (rtl8188eu), and TTY (efm32-uart) drivers. Small fixes were also added to the CIFS, Configfs and Hugetlbfs supported filesystems, and the networking stack was updated to a few improvements to the mac80211 wireless framework.
