[v4,0/4] kernel.h: Split out a couple of macros to args.h

Message

There are macros in kernel.h that can be used outside of that header.
Split them to args.h and replace open coded variants.

Test compiled with `make allmodconfig` for x86_64.
Test cross-compiled with `make multi_v7_defconfig` for arm.

(Note that positive diff statistics is due to documentation being
updated.)

In v4:
- fixed compilation error on arm (LKP, Stephen)

In v3:
- split to a series of patches
- fixed build issue on `make allmodconfig` for x86_64 (Andrew)

In v2:
- converted existing users at the same time (Andrew, Rasmus)
- documented how it does work (Andrew, Rasmus)

Andy Shevchenko (4):
  kernel.h: Split out COUNT_ARGS() and CONCATENATE() to args.h
  x86/asm: Replace custom COUNT_ARGS() & CONCATENATE() implementations
  arm64: smccc: Replace custom COUNT_ARGS() & CONCATENATE()
    implementations
  genetlink: Replace custom CONCATENATE() implementation
