Subject: [PATCH v2 4/5] powerpc/audit: directly include unistd_32.h from compat_audit.c
Date: Mon, 02 Mar 2026 08:58:40 +0100 [thread overview]
Message-ID: <20260302-vdso-compat-checkflags-v2-4-78e55baa58ba@linutronix.de> (raw)
In-Reply-To: <20260302-vdso-compat-checkflags-v2-0-78e55baa58ba@linutronix.de>
This source file undefines '__powerpc64__' to get the 32-bit system call
numbers from asm/unistd.h. However this symbol is also evaluated by
other headers, among them is asm/bitsperlong.h. The undefinition leads
to an inconsistency between __BITS_PER_LONG and the C type 'long'.
An upcoming consistency check will be tripped by this.
Directly include asm/unistd_32.h to get access to the 32-bit system call
numbers instead.
