Subject: [PATCH v3 04/27] uapi: KVM: Provide arm64 UAPI for other host architectures

From: Steffen Eiden <[email-masked]>
Date: Fri, 29 May 2026 17:50:18 +0200

Enable the ARM64 userspace API to be used on non-arm64 host
architectures, with initial support for s390.

The arm64 KVM UAPI headers are relocated to include/uapi/arch/arm64/,
allowing non‑arm64 hosts (such as s390) to use the arm64 KVM userspace API.

To achieve architecture independence, some type aliases are introduced,
which conditionally resolve to native arm64 types when building on arm64
or to fallback to ABI compatible inline struct definitions on other
architectures.

The build system is updated to install the moved UAPI headers to their
original location but in and conditionally export arm64 architecture
headers for s390. This infrastructure enables s390 systems to host arm64
virtual machines while maintaining full compatibility with the existing
arm64 KVM-UAPI, requiring only minimal, compatible changes to the arm64
UAPI-headers itself.
