Russell King 3fba7e23f7 ARM: uaccess: provide uaccess_save_and_enable() and uaccess_restore() ...

Provide uaccess_save_and_enable() and uaccess_restore() to permit
control of userspace visibility to the kernel, and hook these into
the appropriate places in the kernel where we need to access
userspace.
