Subject: [PATCH v4 30/30] KVM: x86: Move a pile of stuff from kvm_host.h => x86.h
Date: Fri, 12 Jun 2026 17:03:29 -0700 [thread overview]
Message-ID: <20260613000329.732085-31-seanjc@google.com> (raw)
In-Reply-To: <20260613000329.732085-1-seanjc@google.com>
Move the majority of remaining KVM-internal declarations and defines in
kvm_host.h to x86.h, so that kvm_host.h only holds structure and function
definitions that need to be visible to arch-neutral KVM.
Land the emulator interfaces in x86.h, even though kvm_emulate.h *seems*
like a good home, as the interfaces and defines being moved are provided by
x86.c. I.e. keep kvm_emulate.h as an interface to the emulator proper.
Note, any "misses" are likely unintentional.
