[RFC PATCH v1 0/3] put arm64 kvm_config on a diet

Hi,

When building guest kernels for virtualisation we were bringing in a
bunch of stuff from physical hardware which we don't need for our
idealised fixable virtual PCI devices. This series makes some Kconfig
changes to allow the ThunderX and XGene PCI drivers to be compiled
out. It also drops PCI_QUIRKS from the KVM guest build as a virtual
PCI device should be quirk free.

This is my first time hacking around Kconfig so I hope I've got the
balance between depends and selects right but please let be know if it
could be specified in a cleaner way.

Alex Bennée (3):
arm64: allow de-selection of ThunderX PCI controllers
arm64: gate the whole of pci-xgene on CONFIG_PCI_XGENE
kernel/configs: don't include PCI_QUIRKS in KVM guest configs
