Subject: [kvm-unit-tests PATCH 01/39] x86/access: Add proper defines for hardcoded addresses
Date: Thu, 25 Nov 2021 01:28:19 +0000	[thread overview]
Message-ID: <20211125012857.508243-2-seanjc@google.com> (raw)
In-Reply-To: <20211125012857.508243-1-seanjc@google.com>

Use defines to differentiate between the paging structure and code/data
physical address ranges to reduce the magic ever so slightly.

No functional change intended.
