The vDSO implementation can only include headers from the vdso/ namespace. To enable the usage of the ALIGN() macro from the vDSO, move linux/align.h to vdso/align.h wholly. As the only dependency linux/const.h is only a wrapper around vdso/const.h anyways adapt that dependency. Also provide a compatibility wrapper linux/align.h.
