Subject: [PATCH 1/3] x86/Kconfig: Move ARCH_HAS_MEM_ENCRYPT to arch/Kconfig
Date: Fri, 12 Jul 2019 02:36:29 -0300
Message-ID: <20190712053631.9814-2-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20190712053631.9814-1-bauerman@linux.ibm.com>

powerpc and s390 are going to use this feature as well, so put it in a
generic location.
