return of page_address in module and copy it to userspace buffer. is there a way

Question

is there a way to copy/map the return of page_address to userspace buffer passed file's read function

what I read is

 page_address() 

returns virtial address of the page. and takes pointer to a page which is of kernel's data type

for example I have a function containing this

void *rx_buf= page_address(arr_pages[i])
char buf[4094];
memcpy(buf,rx_bu,sizeof(page))

can I use memcpy or copy_to_user like

memcpy(buf,rx_buf,sizeof(page));

or

copy_to_user(buf,rx_buf,sizeof(struct page));

what I read copy_to_user does not a allow this, cause if buf is userspace buffer block then it checks the buffer is in the user portion of the memory. also this also prevents userspace applications from asking the kernel to read/write kernel addresses;

so I like to know is there a way to copy the return of page_address to user space buffer
