virtio_net: dpp struggles to translate certain linux system headers (log2.h,init.h,printk.h,swap.h)

[Laeeth]

Alexandru Miltaru gave a dconf talk on writing linux device drivers in D, focusing on replacing virtio_net.c in the kernel. He mentioned some problem with dpp.

Code is here: https://github.com/Laeeth/dlang-safer-linux-kernel-dpp

With 5.01.1 kernel I get the following problems:
