drivers/xen: make [xen-]ballon explicitly non-modular The Makefile / Kconfig currently controlling compilation here is: obj-y += grant-table.o features.o balloon.o manage.o preempt.o time.o [...] obj-$(CONFIG_XEN_BALLOON) += xen-balloon.o ...with: drivers/xen/Kconfig:config XEN_BALLOON drivers/xen/Kconfig: bool "Xen memory balloon driver" ...meaning that they currently are not being built as modules by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. In doing so we uncover two implict includes that were obtained by module.h having such a wide include scope itself: In file included from drivers/xen/xen-balloon.c:41:0: include/xen/balloon.h:26:51: warning: ‘struct page’ declared inside parameter list [enabled by default] int alloc_xenballooned_pages(int nr_pages, struct page **pages); ^ include/xen/balloon.h: In function ‘register_xen_selfballooning’: include/xen/balloon.h:35:10: error: ‘ENOSYS’ undeclared (first use in this function) return -ENOSYS; ^ This is fixed by adding mm-types.h and errno.h to the list. We also delete the MODULE_LICENSE tags since all that information is already contained at the top of the file in the comments.
