From 813fe686e90b433b6d13cfd157b8008825193872 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Sun, 17 May 2026 13:05:05 -1000 Subject: [PATCH] security/Kconfig.hardening: Remove tautological condition from CC_HAS_ZERO_CALL_USED_REGS Now that the minimum supported version of LLVM for building the kernel has been raised to 17.0.1, the '!Clang || Clang > 15.0.6' dependency for CONFIG_CC_HAS_ZERO_CALL_USED_REGS is always true, so it can be removed.
