Linux Kernel 4.14 LTS Officially Released, Supports AMD Secure Memory Encryption

One of the major new features of the Linux kernel 4.14 LTS, however, is the implementation of bigger memory limits in x86 hardware, which bumps the limits to 128PiB of virtual address space and 4PiB of physical address space. This release also introduces a new ORC unwinder to improve the kernel traces and the size of the kernel. Other than that, Linux kernel 4.14 LTS introduces zstd compression for both Btrfs and SquashFS file systems, the ability to zero-copy data from user memory to sockets, improved cpufreq coordination with SMP, asynchronous non-blocking buffered reads, as well as support for the PCID instruction for faster TBL flushing.
