From 8ebb8682f6037f5373862d7ab2f72c2d3e387fbc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Tue, 14 Nov 2023 15:53:26 +0100 Subject: [PATCH] hw/xen/hvm: Propagate page_mask to a pair of functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We are going to replace TARGET_PAGE_MASK by a runtime variable. In order to reduce code duplication, propagate TARGET_PAGE_MASK to get_physmapping() and xen_phys_offset_to_gaddr().
