Subject: [PATCH 0/2] kbuild: userprogs: also inherit byte order and ABI from kernel
Date: Wed, 13 Aug 2025 07:43:39 +0200 [thread overview]
Message-ID: <20250813-kbuild-userprogs-bits-v1-0-2d9f7f411083@linutronix.de> (raw)
Make sure the byte order and ABI of the userprogs matches the one of the
kernel, similar to how the bit size is handled.
Otherwise the userprogs may not be executable.
This happens for example on powerpc little endian, or riscv32.
These patches where originally part of my series "kunit: Introduce UAPI
testing framework" [0], but that isn't going anywhere right now and the
patches are useful on their own.
