[RFT 00/13] iomap: Constify ioreadX() iomem argument
Hi,
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take
pointer to const.
Patchset was really tested on all affected architectures.
Build testing is in progress - I hope auto-buil...

[RFC 0/2] virtio_pci: patches never to apply.
This should allow testing when QEMU gets VIRTIO_PCI_CAP_PCI_CFG support,
but I'm pretty sure we should never allow these patches upstream.
Tested with lguest (in virtio-next), which supports VIRTIO_PCI_CAP_PCI_CFG.
Rusty Russell (2):
virtio_pci: abstract all MMIO accesses.
virtio: Introducing virtio_pci.no_mmio, the worst boot option in
history.
