kernel/linux.git/tools/testing/selftests/powerpc/include, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112025-09-01T07:53:29+00:00powerpc: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-uapi headers2025-09-01T07:53:29+00:00Thomas Huththuth@redhat.com2025-08-01T08:20:07+00:00urn:sha1:74db6cc331b0da5c48c62b7af68d747ec9af1984
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This is bad since macros starting with two underscores are names
that are reserved by the C language. It can also be very confusing
for the developers when switching between userspace and kernelspace
coding, or when dealing with uapi headers that rather should use
__ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__
macro that is provided by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), apart from tweaking two comments manually in
arch/powerpc/include/asm/bug.h and arch/powerpc/include/asm/kasan.h
(which did not have proper underscores at the end) and fixing a
checkpatch error about spaces in arch/powerpc/include/asm/spu_csa.h.

has been queued to arm64/for-next/pkey_unrestricted which is causing a build break
in the selftest/powerpc builds.
Commit 6d61527d931ba ("mm/pkey: Add PKEY_UNRESTRICTED macro") added a macro
PKEY_UNRESTRICTED to handle implicit literal value of 0x0 (which is "unrestricted").
Add the same to selftest/powerpc/pkeys.h to fix the reported build break.

Both core-pkey.c and ptrace-pkey.c tests have
similar macro definitions, move them to "pkeys.h"
and remove the macro definitions from the C file.

Adds _MSG assertion variants to provide more context behind why a

fprintf(), and move ARRAY_SIZE macro to utils.h.
The _MSG variants and ARRAY_SIZE will be used by the following

selftests/powerpc: Allow bind_to_cpu() to automatically pick CPU2023-04-20T03:21:45+00:00Benjamin Graybgray@linux.ibm.com2023-04-06T04:33:16+00:00urn:sha1:6ff4dc25483f3f49d1db48af28d4c485fc77bd21
All current users of bind_to_cpu() don't care _which_ CPU they get, just
that they are bound to a single free one. So alter the interface to
1. Accept a BIND_CPU_ANY value that tells it to automatically
pick a CPU
2. Return the picked CPU
And convert all these users to bind_to_cpu(BIND_CPU_ANY).
