Subject: [PATCHv4 32/33] x86: enable 5-level paging support
Date: Mon, 6 Mar 2017 16:53:56 +0300 [thread overview]
Message-ID: <20170306135357.3124-33-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20170306135357.3124-1-kirill.shutemov@linux.intel.com>
Most of things are in place and we can enable support of 5-level paging.
Enabling XEN with 5-level paging requires more work. The patch makes XEN
dependent on !X86_5LEVEL.
