Subject: [PATCH 11/11] s390/mm: Remove the now unused mem_encrypt_active() function
Date: Tue, 27 Jul 2021 17:26:14 -0500	[thread overview]
Message-ID: <161de897babd0db0f6a10f081fb17e4a93f2f2b6.1627424774.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1627424773.git.thomas.lendacky@amd.com>

The mem_encrypt_active() function has been replaced by prot_guest_has(),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).
