[PATCH v4 00/15] virtio-mem: paravirtualized memory
This series is based on v5.7-rc4. The patches are located at: https://github.com/davidhildenbrand/linux.git virtio-mem-v4 This is basically a resend of v3 [1], now based on v5.7-rc4 and restested. One patch was reshuffled and two ACKs I missed to add were added. The rebase did not require any modifications to patches. Details about virtio-mem can be found in the cover letter of v2 [2]. A

[PATCH] virtio_mem: prevent overflow with subblock size
If subblock size is large (e.g. 1G) 32 bit math involving it can overflow. Rather than try to catch all instances of that, let's tweak block size to 64 bit. It ripples through UAPI which is an ABI change, but it's not too late to make it, and it will allow supporting >4Gbyte blocks while might become necessary down the road.

[PATCH v2 00/24] virtio: config space endian-ness cleanup
Config space endian-ness is currently a mess: fields are not tagged with the correct endian-ness so it's easy to make mistakes like instanciating config space in native endian-ness. The following patches adding sparse tagging are currently in my tree. Lightly tested. As a follow-up, I plan to add new APIs that handle modern config space in a more efficient way (bypassing the version check).
