For those not keeping up to date on all of the Phoronix articles covering the Linux 3.15 kernel changes that landed in the past week, here's a recap of the changes that were merged so far half-way through the Linux 3.15 merge window.

- EFI mixed mode support to allow 64-bit Linux kernels to be booted from 32-bit system UEFI firmwares.

- AVX-512 instruction support for future Intel processors.

- AHCI libata improvements.

- Scheduler improvements.

- The mainline Linux kernel can almost be exploited for better performance through link-time optimization support for the kernel.

- Performance and bug-fixes for the Btrfs file-system.

- Many audio/sound improvements.

- ACPI and power management improvements, particularly better support for new hardware and ACPI improvements.

- Support was dropped for old x86 platforms.

- Kernfs is in better shape for other subsystems wishing to utilize this sysfs-derived code.

- Better Windows guest support for KVM virtualization.

- New input device support for the Linux 3.15 kernel, including Sony's DualShock 4 controller for the PlayStation 4.

- Better write performance with the FUSE file-systems in user-space.

- Intel RDSEED support for better randomness.

- EXT4 and XFS file-system updates.

- New media/V4L2 drivers.

- ARM SoC updates.

There's still several more days left to the Linux 3.15 merge window before Linux 3.15-rc1 is declared, including the DRM pull and other interesting merges, so stay tuned for the latest Linux kernel updates on Phoronix.
