From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is the best summary I could come up with:
Due to the ARM64 maintainer for the Linux kernel going on holiday, the ARM64 port updates have been submitted ahead of the opening of the Linux 6.11 merge window that will likely be on Monday or otherwise the following week depending upon if a 6.10-rc8 is warranted.
When it comes to the ARM64 (AArch64) changes for this next kernel version, there's been a lot of work on virtual CPU hotplug handling so that it should now be properly working on ARM64 ACPI-enabled systems.
Another change with Linux 6.11 ARM64 is expanding the speculative SSBS workaround to more CPU cores.
Arm's Speculative Store Bypass handling is now being extended for additional affected CPU cores of he A710, A720, X2, X3, X925, N2, and V2.
There are also ARM64 ACPI updates, GICv3 optimizations, perf updates for more hardware, and other smaller changes.
See this merge request for all the ARM64 feature patches slated for Linux 6.11.
