I've also intentionally not turned on the gcc support, as discussed on v1. As this was lifted from the state of the Rust-for-Linux tree, the commit messages from there cannot be preserved, so these patches have commit messages that I wrote. I've tested this on Icicle, and the modules seem to work as expected. Unfortunately there appear to be implicit 32-bit divisions (or similar) in core Rust code, so, as in the downstream Rust-for-Linux tree, Rust is only enabled for 64-bit. Thanks, Conor. Changes in v2: - Rebase, since a good bit of time has passed! - Add the extra patch, disabling when CFI_CLANG is enabled. Changes in v1: - rebase on v6.3-rc1 - resort the `um` entry in the arch-support table while adding RISC-V to it - drop 32-bit bits - have another crack at assigning authorship Changes in RFC-RESEND: - fix the asymmetrical additions in the Makefile bits - add cc-cover to my git send-email command...
