From e9d1d2bb75b2d5d4b426769c5aae0ce8cef3558f Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Wed, 8 Sep 2021 17:58:39 -0500 Subject: treewide: Replace the use of mem_encrypt_active() with cc_platform_has() 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).
