Modified files: sys/arch/amd64/amd64: cpu.c Log message: We don't save+restore FS.base and GS.base on every context switch but rather reset GS.base and restore FS.base to what was set via __tcb_set(), so we can't really support the wr{fs,gs}base instructions by userspace. Enabling CR4_FSGSBASE is therefore incorrect so stop doing so. ok jsg@ krw@
