The ARM64 architecture updates were sent in on Monday for the Linux 4.7 kernel and do contain some notable changes.

The ARM64 code in Linux 4.7 is bringing support for system hibernate and suspend-to-disk as the most notable additions. The ARM64 code also adds proper support for using the maxcpus= command-line parameter, detection and proper handling of AArch64-only CPUs, support for NUMA systems described via DeviceTree, some optimizations, and other clean-ups and fixes.

Those wanting to learn more about the ARM64 hibernate/suspend-to-disk support can see its individual patch series. The complete list of ARM64 Linux 4.7 changes overall can be found via the pull request sent in by Will Deacon.
