From 5659b598b4dcb352b1a567c55fc5a658bc80076c Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Thu, 8 Sep 2022 14:54:57 -0700 Subject: [PATCH] treewide: Drop __cficanonical CONFIG_CFI_CLANG doesn't use a jump table anymore and therefore, won't change function references to point elsewhere. Remove the __cficanonical attribute and all uses of it. Note that the Clang definition of the attribute was removed earlier, just clean up the no-op definition and users.
