Back in 2021 AMD began preparing Linux kernel support for 5-level paging support with their future processors and building off the prior 5-level page table kernel support established by Intel. That was followed by AMD enabling 5-level page table support with KVM SVM in the Linux 5.15 kernel. AMD CPUs with 5-level page table support since launched in the form of 4th Gen EPYC "Genoa" processors. One piece only now coming together though is AMD IOMMU driver support for 5-level guest page table support...

As noted back in March, the plan with Linux 6.4 is to start removing old, unused and unmaintained PCMCIA drivers. As part of that process to begin dropping old PCMCIA/CardBus driver code from the kernel, all of the PCMCIA "char" drivers were on the chopping block. Linus Torvalds pulled in the char/misc changes this week for Linux 6.4 and indeed those drivers are now removed. Meanwhile this pull introduced the new AMD CDX subsystem...
