From 82bf7ae84ce739e77bba4f9b628ae799c5f204f6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 4 Sep 2020 16:41:55 +0100 Subject: target/arm: Remove KVM support for 32-bit Arm hosts We deprecated the support for KVM on 32-bit Arm hosts in time for release 5.0, which means that our deprecation policy allows us to drop it in release 5.2. Remove the code. To repeat the rationale from the deprecation note: the Linux kernel dropped support for 32-bit Arm KVM hosts in 5.7. Running 32-bit guests on a 64-bit Arm host remains supported.
