Subject: [PATCH v3 8/8] treewide: Replace the use of mem_encrypt_active() with cc_platform_has()
Date: Wed, 8 Sep 2021 17:58:39 -0500 [thread overview]
Message-ID: <46a18427dc4e9dda985b10e472965e3e4c769f1d.1631141919.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1631141919.git.thomas.lendacky@amd.com>
Replace uses of mem_encrypt_active() with calls to cc_platform_has() with
the CC_ATTR_MEM_ENCRYPT attribute.
Remove the implementation of mem_encrypt_active() across all arches.
For s390, since the default implementation of the cc_platform_has()
matches the s390 implementation of mem_encrypt_active(), cc_platform_has()
does not need to be implemented in s390 (the config option
ARCH_HAS_CC_PLATFORM is not set).
