    ARM: move signal handlers into a vdso-like page · 48be69a0

    Move the signal handlers into a VDSO page rather than keeping them in
    the vectors page.  This allows us to place them randomly within this
    page, and also map the page at a random location within userspace
    further protecting these code fragments from ROP attacks.  The new
    VDSO page is also poisoned in the same way as the vector page.
