Subject: [PATCH 1/3] x86, s390: Move ARCH_HAS_MEM_ENCRYPT definition to arch/Kconfig
Date: Sat, 13 Jul 2019 01:45:52 -0300 [thread overview]
Message-ID: <20190713044554.28719-2-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20190713044554.28719-1-bauerman@linux.ibm.com>
powerpc is also going to use this feature, so put it in a generic location.
