Hi, I've done the following, hopefully it will enable others.
Completed: - Builds amd64 tools - Builds working amd64 kernel (*without new mitigations*!) Need: - Test full release, stress test - Test i386 too - Decide which spectre mitigation to use - Test that kernel with that mitigation works - Also, modules! - Run the new testcases from GCC testsuite which were added with this feature Maybe: - Figure out what I just did to the documentation? Patch: http://netbsd.org/~maya/netbsd8-gcc-spectre-20180312 (Originally from opensuse's gcc patch, and comparing a lot to gcc-HEAD where it was insufficient)
