Thanks for the patches.

FYI, `make defconfig custom.config` doesn't work as expected with the Xen
build system, it doesn't deal with this use case like Linux's one does.
There is no guaranty that "defconfig" will be made before "custom.config".
It would be better to run `make defconfig && make custom.config`, or
maybe use -j1, until this is properly handled. That's what is done by
