The framebuffer is needlessly mapped (PROT_READ | PROT_WRITE), map it PROT_READ instead. The framebuffer is unmapped by replacing the framebuffer pages with anonymous shared memory, calling mmap. Check for return errors and print a warning. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
