Hi Kishon,

I didn't see this error when I built pcitest with your dma patch for x86_64
on Ubuntu 16.04 (xenial) and Debian 9.9 (stretch). Same for riscv. The
following output is from my Ubuntu machine:

$ cd ~/src/kernel.org/linux
$ cd tools/pci
$ ls
Build  Makefile  pcitest.c  pcitest.sh
$ make
mkdir -p include/linux/ 2>&1 || true
ln -sf /home/sfnuc/src/kernel.org/linux/tools/pci/../../include/uapi/linux/pcitest.h
include/linux/
make -f /home/sfnuc/src/kernel.org/linux/tools/build/Makefile.build
dir=. obj=pcitest
make[1]: Entering directory '/home/sfnuc/src/kernel.org/linux/tools/pci'
  CC       pcitest.o
  LD       pcitest-in.o
make[1]: Leaving directory '/home/sfnuc/src/kernel.org/linux/tools/pci'
  LINK     pcitest
$ ls
Build  include  Makefile  pcitest  pcitest.c  pcitest-in.o  pcitest.o
pcitest.sh

Regards,
Alan
