Subject: [PATCH v2 2/3] selftest: kvm: Move struct kvm_x86_state to header
Date: Wed, 22 Dec 2021 16:47:30 -0500	[thread overview]
Message-ID: <20211222214731.2912361-3-yang.zhong@intel.com> (raw)
In-Reply-To: <20211222214731.2912361-1-yang.zhong@intel.com>

Those changes can avoid dereferencing pointer compile issue
when amx_test.c reference state->xsave.

Move struct kvm_x86_state definition to processor.h.
