Linux Looking To Make 5-Level Paging Support Unconditional For x86_64 Kernel Builds

It's been nearly one decade since Intel began working on 5-level paging support for the Linux kernel to allow for greater virtual and physical address space with expanding memory sizes. The 5-level paging kernel-side bits were upstreamed back in Linux 4.12 in 2017 and enabled by default since 2019 with Linux 5.5. Intel CPUs for a while (since Ice Lake) have supported 5-level paging and AMD CPUs too since Zen 4. The Linux kernel may move to unconditionally enabling 5-level paging support for x86_64 kernel builds...

getrandom() In The vDSO Aims For Linux 6.11 To Provide Faster Yet Secure User-Space RNG

In the making the past two years by developer Jason Donenfeld (of WireGuard fame) is adding getrandom() to the vDSO in the name of better performance. In some tests this has yielded as much as a ~15x speed-up to performance for user-space obtaining crypographically secure random number generation. It's looking like for the upcoming Linux 6.11 merge window, this work will finally be merged...
