The QAT acceleration card can be very helpfull for some tasks like dealing
with IPSEC but it is currently restricted to be used only on x86 machine.
Looking at the code we didn't see any reasons why those drivers might not
work on other architectures. We've successfully built all of them on x86,
arm64, arm32, mips64, powerpc64, riscv64 and sparc64.

We also have tested the driver with an Intel Corporation C62x Chipset
QuickAssist Technology (rev 04) PCIe card on an arm64 server. After the numa
patch, it works with the AF_ALG crypto userland interface, allowing us to
encrypt some data with cbc for instance. We've also successfully created some
VF, bound them to DPDK, and used the card this way, thus showing some real
life usecases of x86 do work on arm64 too.

Changelog v1 ... v2:
- add COMPILE_TEST to Kconfig

Andre Przywara (1):
  crypto: qat: replace get_current_node() with numa_node_id()

  Removes the x86 dependency on the QAT drivers

Would you mind re-sending the set changing the headline of the commit
