However, if a non-TLS definition of the symbol in question is visible in the same compilation unit (which amounts to the whole of vmlinux if LTO is enabled), it will drop the per-CPU prefix and emit a load from a bogus address.

I take this to mean that x86 32-bit kernels built with the stack protector and using Clang LTO will crash very quickly?
