[PATCH] x86/build: Raise the minimum LLVM version to 15.0.0
From: Nathan Chancellor
Date: Thu Feb 20 2025 - 15:08:44 EST
In a similar vein as commit a3e8fe814ad1 ("x86/build: Raise the minimum
GCC version to 8.1"), bump the minimum supported version of LLVM for
building x86 kernels to 15.0.0, as that is the first version that has
support for '-mstack-protector-guard-symbol', which is used
unconditionally after commit 80d47defddc0 ("x86/stackprotector/64:
Convert to normal per-CPU variable"):
clang-14: error: unknown argument: '-mstack-protector-guard-symbol=__ref_stack_chk_guard'
Fixes: 80d47defddc0 ("x86/stackprotector/64: Convert to normal per-CPU variable")
