[PATCH 5.1 093/115] kvm: selftests: aarch64: fix default vm mode

From: Greg Kroah-Hartman
Date: Mon Jun 17 2019 - 17:28:48 EST


[ Upstream commit 55eda003f02f075bab0223a188e548dbf3ac8dfe ]

VM_MODE_P52V48_4K is not a valid mode for AArch64. Replace its
use in vm_create_default() with a mode that works and represents
a good AArch64 default. (We didn't ever see a problem with this
because we don't have any unit tests using vm_create_default(),
but it's good to get it fixed in advance.)
