Subject: [PATCH 07/13] KVM: x86: Refactor init_emulate_ctxt() to explicitly take context
Date: Fri, 22 Nov 2019 14:39:53 -0800	[thread overview]
Message-ID: <20191122223959.13545-8-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191122223959.13545-1-sean.j.christopherson@intel.com>

Explicitly pass the emulation context when initializing said context in
preparation of dynamically allocation the emulation context.
