Modified Files: src/sys/arch/x86/x86: cpu.c pmap.c svs.c Log Message: Change the effect of SVS on the TLB. Keep CR4_PGE set when SVS is enabled, but don't use PTE_G on the kernel PTEs in general. Add PTE_G on only a few pages, that are already leaked to userland and do not contain secrets. This slightly improves syscall performance.
