Ignore the vector page in /proc/<pid>/maps
In kernel 2.6.37, the vector page was added to /proc/<pid>/maps,
but because it is located above TASK_SIZE (usually 0xbf000000),
it is considered to be in the kernel's address space, not the
process', so it doesn't show up in /proc/<pid>/pagemap.
When the vector page is detected, using the name "[vectors]",
remove it from the map.
