Subject: [PATCH for-next v3 10/12] x86/domain: move HVM specific code to hvm/domain.c
Date: Wed, 26 Apr 2017 16:54:55 +0100 [thread overview]
Message-ID: <20170426155457.10799-11-wei.liu2@citrix.com> (raw)
In-Reply-To: <20170426155457.10799-1-wei.liu2@citrix.com>
There is only one function arch_set_info_hvm_guest is moved. The
check_segment function is also moved since arch_set_info_hvm_guest is
the only user.
No functional change.
