Subject: [PATCH v3 2/6] swiotlb: Remove call to sme_active()
Date: Thu, 18 Jul 2019 00:28:54 -0300	[thread overview]
Message-ID: <20190718032858.28744-3-bauerman@linux.ibm.com> (raw)
In-Reply-To: <20190718032858.28744-1-bauerman@linux.ibm.com>

sme_active() is an x86-specific function so it's better not to call it from
generic code.

There's no need to mention which memory encryption feature is active, so
just use a more generic message. Besides, other architectures will have
different names for similar technology.
