(0) We list the ARCHs which support the NUMA:
arm64, loongarch, powerpc, riscv,
sparc, mips, s390, x86,
(1) Some ARCHs in (0) override the generic cpu_to_node(), such as:
sparc, mips, s390, x86.
Since these ARCHs have their own cpu_to_node(), we do not care
about
Some devices are not capable of addressing 64 bits
via DMA, which includes MSI-X vectors. This allows
us to ensure these devices use MSI-X vectors in
32 bit space.

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
