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

From: Andy Shevchenko
Date: Tue Jul 18 2023 - 17:11:56 EST


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
