- Radeon Userptr support.
- Numerous Intel graphics enhancements across the board.
- Nouveau DisplayPort audio, other re-clocking work, and various other enhancements for this open-source NVIDIA driver.
- Other DRM improvements.
Linux Hardware:
- Many new media drivers.- New support for ARM SoCs on Linux.
- AMD Carrizo thermal monitoring.
- Razer Sabertooth support and other input device improvements.
- Wacom tablet enhancements.
- ACPI and power management improvements.
- PCI support on 64-bit ARM (ARM64/AArch64).
- Faster suspend and resume on large servers / many CPU cores.
File-Systems:
- Btrfs improvements with recovery and repair in RAID configurations being notable.- F2FS additions like FITRIM support, atomic/volatile writes, and much more.
- Many minor XFS improvements.
- Cleaning and bug fixing happened for EXT4.
- The mailbox framework has finally been mainlined.
Etc:
- Xen PVSCSI support.- Firmware core-dumps to user-space via sysfs for allowing better debugging of GPU/WiFi microcode issues and other complex firmware problems.
- USB improvements.
- 64-bit ARM is more friendly to Clang although the mainline Linux kernel can't yet build under LLVM/Clang on any architecture quite yet. There's also other LLVMLinux/Clang-compatible alterations that landed in Linux 3.18 outside of the AArch64 work.
