[PATCH] Add install_special_mapping
This patch adds a utility function install_special_mapping, for creating a
special vma using a fixed set of preallocated pages as backing, such as for a
vDSO. This consolidates some nearly identical code used for vDSO mapping
reimplemented for different architectures.
