From eae446b7654f25b2ca42ed0de54d7005e126fdac Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Thu, 28 Oct 2021 10:12:21 +0200 Subject: [PATCH] x86/xen: remove 32-bit awareness from startup_xen startup_xen is still 32-bit aware, even if no longer needed. Replace the register macros by the 64-bit register names for making it more readable.
