Hi Greg,
Some platforms don't have DMA, but we should still be able to build USB
drivers for these platforms. They could still be used through vhci_hcd,
usbip_host, or maybe something like USB passthrough in UML from a
capable host.
This patch series allows to compile USB on platforms where NO_DMA=y.
I've been using it for quite a while to make allmodconfig/allyesconfig
build for m68k/sun3.
Vegard used this on UML to read a USB flash drive plugged into the host
machine using USB-over-IP.
Changes compared to v1:
- Replace remaining #ifdefs by IS_ENABLED() checks,
- Add to patch description that this actually allows using USB on UML,
- Add Acked-by.
Thanks!

If NO_DMA=y:

Add a few checks for CONFIG_HAS_DMA to fix this.

This patch didn't apply to my tree, can you rebase it against usb-next
of usb.git and resend?

Are you sure it's this one that didn't apply? It's already in usb-testing?
"[2/3] usb: host: Host drivers relying on DMA should depend on HAS_DMA"
doesn't apply, as your tree gained some HAS_IOMEM dependencies, so I'll
resend.
