From: Conor Dooley <conor.dooley@microchip.com>
On RISC-V and arm64, and presumably x86, if CFI_CLANG is enabled, loading a rust module will trigger a kernel panic. Support for sanitisers, including kcfi (CFI_CLANG), is in the works, but for now they're nightly-only options in rustc. Make RUST depend on !CFI_CLANG to prevent configuring a kernel without symmetrical support for kfi.
Fixes: 2f7ab1267dc9 ("Kbuild: add Rust support") cc: stable@vger.kernel.org Signed-off-by: Conor Dooley <conor.dooley@microchip.com> --- Sending this one on its own, there's no explicit dep on this for the riscv enabling patch, v3 to continue the numbering from there. Nothing has changed since v2.
