Any function that is exported in the kernel can be called from a module. There is no list. To learn about the functions that are available, you should read source code that is related to what you are doing, read books, and read any available documentation. As for how to allocate memory: - kmalloc(): Allocate some memory that is physically contiguous (and I believe also virtually contiguous). Should only be used for smaller allocations. - vmalloc(): Allocate some memory that is virtually contiguous, usually used for larger allocations where there may not be enough contiguous physical memory. - alloc_pages(): return a number of virtually contiguous pages. - __get_free_pages(): same as alloc_pages(), but returns the starting address of the region instead of the page structure of the first page. - alloc_page() / __get_free_page(): save as above 2 functions, but for one page.
