Subject: [PATCH v5 03/24] KVM: arm64: Include KVM headers to get forward declarations
Date: Tue,  9 Dec 2025 20:51:00 +0000	[thread overview]
Message-ID: <20251209205121.1871534-4-coltonlewis@google.com> (raw)
In-Reply-To: <20251209205121.1871534-1-coltonlewis@google.com>

From: Sean Christopherson <seanjc@google.com>

Include include/uapi/linux/kvm.h and include/linux/kvm_types.h in ARM's
public arm_arch_timer.h and arm_pmu.h headers to get forward declarations
of things like "struct kvm_vcpu" and "struct kvm_device_attr", which are
referenced but never declared (neither file includes *any* KVM headers).

The missing includes don't currently cause problems because of the order
of includes in parent files, but that order is largely arbitrary and is
subject to change, e.g. a future commit will move the ARM specific headers
to arch/arm64/include/asm and reorder parent includes to maintain
alphabetic ordering.
