From: Tom Lendacky <thomas.lendacky@amd.com>
Date: 2021-07-27 22:28:55
Also in: amd-gfx, dri-devel, kexec, kvm, linux-fsdevel, linux-iommu, linux-s390, linuxppc-dev, lkml, platform-driver-x86
Subsystem: s390 architecture, the rest · Maintainers: Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Linus Torvalds

The mem_encrypt_active() function has been replaced by prot_guest_has(),
so remove the implementation. Since the default implementation of the
prot_guest_has() matches the s390 implementation of mem_encrypt_active(),
prot_guest_has() does not need to be implemented in s390 (the config
option ARCH_HAS_PROTECTED_GUEST is not set).
