Good news: make allyesconfig;make succeed after the changes until this
point, but:
$ grep -R pci_pool
...
drivers/usb/gadget/udc/pch_udc.c: * -ENOMEM: pci_pool_alloc
invocation fails
drivers/usb/host/oxu210hp-hcd.c: * pci_pool consistent memory

uses segment zero.
drivers/usb/host/ehci-hcd.c: * pci_pool consistent memory always
uses segment zero.

this can be updated or removed, needs to check:
