Konstantin Belousov 6f1fe3305a amd64: Add md process flags and first P_MD_PTI flag. ... PTI mode for the process pmap on exec is activated iff P_MD_PTI is set. On exec, the existing vmspace can be reused only if pti mode of the pmap matches the P_MD_PTI flag of the process. Add MD cpu_exec_vmspace_reuse() callback for exec_new_vmspace() which can vetoed reuse of the existing vmspace. MFC note: md_flags change struct proc KBI.
