scripts: headers_install.sh: Remove config leak ignore machinery

2026-01-30T15:46:17+00:00

There are no entries left to ignore and none should be added again.

Remove the now unused logic.

x86/uapi: Stop leaking kconfig references to userspace

2026-01-30T15:46:17+00:00

UAPI headers are not supposed to leak references to kconfig symbols.
These won't be set when building userspace. Hide the kconfig reference
behind 'if defined(__KERNEL__)', so it will be stripped by
headers_install.sh. The result for userspace will be the same, but the
exceptions in headers_install.sh can also be removed.

nios2: uapi: Remove custom asm/swab.h from UAPI

2026-01-30T15:46:17+00:00

UAPI headers are not supposed to leak references to kconfig symbols.
They are undefined there in any case. As all actual definitions of this
header are guarded behind a kconfig symbol, for userspace the header is
always identical to its asm-generic variant.

Make the custom UAPI header a kernel-internal one, so the leaks of
kconfig symbols are fixed and userspace will instead use
asm-generic/swab.h directly.

ARM: uapi: Drop PSR_ENDSTATE

2026-01-30T15:46:17+00:00

The symbol PSR_ENDSTATE is pointless for userspace. Drop it from the
UAPI headers and instead inline it into the only two callers.

As as side-effect, remove a leak of an internal kconfig symbol through
the UAPI headers.

ARC: Always use SWAPE instructions for __arch_swab32()

2026-01-30T15:46:17+00:00

Since commit 67a697e7576 ("ARC: retire ARC750 support") all supported
CPUs have the 'swape' instruction.

Always use the implementation of __arch_swabe() which uses 'swape'.
ARCH_USE_BUILTIN_BSWAP can not be used as that results on libcalls on
-mcpu=arc700.

As as side-effect, remove a leak of an internal kconfig symbol through
the UAPI headers.

scripts: headers_install.sh: Remove two outdated config leak ignore entries

2025-11-11T15:01:13+00:00

Remove config leak ignore entries for arch/arc/include/uapi/asm/page.h
as they have been removed in commit d3e5bab923d3 ("arch: simplify
architecture specific page size configuration").

uapi: wrap compiler_types.h in an ifdef instead of the implicit strip

2025-08-28T11:06:48+00:00

The uAPI stddef header includes compiler_types.h, a kernel-only
header, to make sure that kernel definitions of annotations
like __counted_by() take precedence.

There is a hack in scripts/headers_install.sh which strips includes
of compiler.h and compiler_types.h when installing uAPI headers.
While explicit handling makes sense for compiler.h, which is included
all over the uAPI, compiler_types.h is only included by stddef.h
(within the uAPI, obviously it's included in kernel code a lot).

Remove the stripping from scripts/headers_install.sh and wrap
the include of compiler_types.h in #ifdef __KERNEL__ instead.
This should be equivalent functionally, but is easier to understand
to a casual reader of the code. It also makes it easier to work
with kernel headers directly from under tools/

m68k: Avoid CONFIG_COLDFIRE switch in uapi header

2024-05-06T22:55:23+00:00

We should not use any CONFIG switches in uapi headers since
these only work during kernel compilation. They are not defined
for userspace. Let's use the __mcoldfire__ switch from the
compiler here instead.

hexagon: Remove CONFIG_HEXAGON_ARCH_VERSION from uapi header

2023-11-23T09:38:58+00:00

uapi headers should not expose CONFIG switches since they are not
available in userspace. Fix it in arch/hexagon/include/uapi/asm/user.h
by always defining the cs0 and cs1 entries instead of pad values.

hexagon: Remove unusable symbols from the ptrace.h uapi

2023-10-25T13:54:24+00:00

Kernel-internal prototypes, references to current_thread_info()
and code hidden behind a CONFIG_HEXAGON_ARCH_VERSION switch are
certainly not usable in userspace, so this should not reside
in a uapi header. Move the code into an internal version of
ptrace.h instead.
