Subject: Fix gate_vma.vm_flags
From: Roland McGrath <roland@xxxxxxxxxx>
This patch fixes the initialization of gate_vma.vm_flags and
gate_vma.vm_page_prot to reflect reality. This makes the "[vdso]" line in
/proc/PID/maps correctly show r-xp instead of ---p, when gate_vma is used
(CONFIG_COMPAT_VDSO on i386).
