Linux 5.19 is released, largely with more hardware support and new architectures (including an unusual super-modern virtual Motorola 68000 platform to emulate Google Goldfish devices — my real Q800, clockchipped running A/UX, is flabbergasted). Here's a full list of changes.
This release doesn't have a great deal of Power ISA-specific improvements, but one generally positive note can be implied from Linus Torvalds' announcement message: he's now on an Apple silicon laptop, running Asahi Linux. Recall that Asahi Linux uses 16K pages as opposed to 4K pages, and this is still the case; many Power ISA workstation users are on systems that use 64K pages, including this Raptor Talos II running Fedora 36. If software bustage is happening for Linus himself, then it's a good sign that more software will start becoming more flexible about allowing larger memory pages and that's good news for us niche configurations too.
