kbuild: uapi: Drop types.h check from headers_check.pl

2025-11-08T11:18:00+00:00

Since commit d6fc9fcbaa65 ("kbuild: compile-test exported headers to ensure they are self-contained"), the UAPI headers are compile tested standalone with the compiler. This compile testing will catch a missing include of types.h, making the types.h checking in headers_check.pl originally added in commit 483b41218fa9 ("kbuild: add checks for include of linux/types in userspace headers") obsolete.

kbuild: uapi: reuse KBUILD_USERCFLAGS

2025-11-08T11:17:59+00:00

The toplevel Makefile already provides the compiler flags necessary to build userspace applications for the target. Make use of them instead of duplicating the logic.

kbuild: uapi: Strip comments before size type check

2025-10-06T18:31:19+00:00

On m68k, check_sizetypes in headers_check reports: ./usr/include/asm/bootinfo-amiga.h:17: found __[us]{8,16,32,64} type without #include This header file does not use any of the Linux-specific integer types, but merely refers to them from comments, so this is a false positive. As of commit c3a9d74ee413bdb3 ("kbuild: uapi: upgrade check_sizetypes() warning to error"), this check was promoted to an error, breaking m68k all{mod,yes}config builds. Fix this by stripping simple comments before looking for Linux-specific integer types.

kbuild: hdrcheck: fix cross build with clang

2025-03-04T19:06:45+00:00

The headercheck tries to call clang with a mix of compiler arguments that don't include the target architecture. When building e.g. x86 headers on arm64, this produces a warning like clang: warning: unknown platform, assuming -mfloat-abi=soft Add in the KBUILD_CPPFLAGS, which contain the target, in order to make it build properly.
