vdso/datapage.h includes a lot of headers which are not strictly necessary. Some of those headers include architecture-specific vDSO headers which prevent the usage of vdso/datapage.h in kernel code on architectures without an vDSO. This would be useful however to write generic code using IS_ENABLED(), for example in drivers/char/random.c.
Remove the unnecessary includes.
