Description of problem:

Two sperated issue here:

1. kabi broken after commit d7d8a3ef9b0d316fc5718d3243aa48b858fd1c1d
(anolis: phytium: pswiotlb: Add PSWIOTLB mechanism to improve DMA performance)
with CONFIG_PSWIOTLB=y.

2. CK_KABI_USE(1, struct foo *a) not worked and build error since `COUNT_ARGS`
was move to linux/args.h after commit b229baa374dbb1bb47dccad2cc8887d9438ca3e7
(kernel.h: split out COUNT_ARGS() and CONCATENATE() to args.h)
